These glamorous women experience the ups and downs of motherhood in front of the entire world. They are scrutinized and judged on a regular basis, and every parenting decision they make is picked apart by people who have never even met them.

Even so, many famous mamas continue to smile in spite of the haters. As a result, these stunning stars have shown their sons and daughters how to handle the challenges they face in life with class, grace and style.

14 Ryan Reynolds: "When we had that baby, I fell more in love with my wife than I'd ever been in my entire life."

Ryan Reynolds and Blake Lively are two of the most ridiculously good looking and hilarious humans to ever exist. It only makes sense that the two would get married, procreate, and bring beautiful babies into the world. When they had children, their enviable relationship only got sweeter.

Soon after Lively gave birth for the first time, Reynolds spilled some of the details about their first born's delivery to Conan O'Brien. He dished, "My wife...is a mercenary. At one point in the middle of the delivery, the doctor's cell phone went off and she said, 'Oh no. Go ahead, take a personal call. Feel free.' She was cracking jokes in the delivery room."

It's clear that Reynolds adores Lively, but he made sure the world knew just how much when he shared on the Late Show with David Letterman, "I'm not one for vomiting declarations of sentiment out across the airwaves, but when we had that baby, I fell more in love with my wife than I'd ever been in my entire life. I couldn't even believe it."

Speaking about Blake's parenting prowess, he has shared, "I'm just a diaper-changing facility hooked up to a life-support system, but my wife, she's breakfast, lunch, and dinner. She's a human Denny's all day long ... and it never ends for her. She's the most beautiful Denny's you've ever seen though, I guarantee it."

13 Ashton Kutcher: "She's the greatest mom."

Ashton Kutcher and Mila Kunis first connected when Kutcher gave the actress her first kiss on the set of That '70s Show. The two moved on with their lives and had other relationships, but, eventually, fate brought them back together and the world rejoiced. They have since had two children together: a daughter named Wyatt and a son named Dmitri.

Kutcher opened up about Mila's natural ability to be a mom when he appeared on The Ellen DeGeneres Show soon after Wyatt's arrival. He revealed, "The most amazing thing about having a baby is my partner, Mila. She’s the greatest mom. I go to work every day, and I come home and she’s perfect. And it just seems like everything went amazing. And I know that something probably didn’t go amazing, but she never tells, it’s unbelievable. She’s incredible.”

Kutcher also revealed on Late Night with Conan O'Brien that he and his lady love have chosen to do the dirty work when it comes to raising their tots. He shared, "We're really privileged that we have time and can afford to take time. We don't have a nanny or a night nurse or anything. It's just the two of us." 

The actor continued, “We just want to know our kid. We want to be the people that know what to do when the baby’s crying to make the baby not cry anymore. We want to know, like, when she makes a little face or something, we want to be emotionally in touch with her.”

Speaking about parenthood, Kutcher told Jimmy Kimmel, "It's so good, so good. It's the best thing I've ever done." 

12 Ryan Gosling: "It's like walking through a field of flowers every day."

Ryan Gosling and Eva Mendes have two beautiful daughters together. The pair is extremely private, and have chosen to shield their children from the glitz, glamour and intensity of Hollywood as much as possible. Even so, Ryan can't resist publicly praising his wonderful wife from time to time.

Speaking about his life with Mendes and his two daughters, Gosling gushed to Good Morning America's Amy Robach, "It's heaven. It's like walking through a field of flowers every day. I live with angels."

The dapper dad knows he is one lucky fellow. He has also shared, "You hear what it's like to have kids, and all the clichés are true. I felt I knew that everything would be different, but until you experience that, there's no way to really know what people mean...I only know what it's like to have my kids, and in my situation, Eva's the dream mother, and they're dream babies, and it's like a dream that I'm having right now. I'm dreaming it all. So I feel so lucky."

Gosling has also admitted that parenthood can be chaotic, but he welcomes the craziness. According to the actor, "There's a kind of chaos in it that I love. Maybe in my life I sort of put myself in situations that were chaotic, outside of my life. And now I have it at home, and I don't have to go looking for it."

11 Justin Timberlake: "GREATEST mommy and wife a man could ever ask for."

Justin Timberlake and Jessica Biel are most definitely the epitome of relationship goals. Their adorable son Silas is one lucky little lad. His parents are crazy about each other, and Timberlake takes every opportunity available to him to let his wife, and the world, know what a wonderful mother he thinks she is.

On Biel's birthday, the "Filthy" singer wrote on Instagram, "Happy BAE-DAY, baby!! I can't put into words what you mean to me... You are the GREATEST Mommy and Wife a man could ever ask for. I love you to the MOON AND BACK!!! --Your Huz."

The singer took to Instagram once again on Mother's Day to pay tribute to his one and only. He wrote, "I marvel at you. It's so hard to put into words EVERYTHING a Mother does. And, you do it with such grace. Thank you for giving me the greatest gift and continuing to show him what it means to be a good person in the world. You make me realize how much my own Mother has done for me. #HappyMothersDay to you, my love. And, to my wonderful Mother and all the Moms all over the world: Y'all really DO RUN THIS... I bow down to you." 

10 Jared Kushner: "Ivanka defines the phrase 'hands on.'"

Jared Kushner and Ivanka have three beautiful babies together. Since before Ivanka's father and current President of the United States took up residence in the White House, she has been one of his most trusted advisors, advocates and supporters. The couple's children, Arabella, Joseph and Theodore, are kept out of the spotlight the majority of the time, and the family's private life is largely kept under wraps, but Kushner couldn't resist bragging a bit about his amazing wife in a recent issue of Variety that celebrated New York's powerful young influencers.

Kushner wrote, “Whether preparing to deliver a speech to tens of millions of people at the Republican National Convention, or teaching our kids to swim, Ivanka defines the phrase ‘hands on.'"

Kushner also shared that it is incredible for him to see his wife to handle everything on her plate with grace without ever giving in to the pressure of all she juggles on a daily basis. He is so impressed with her ability to run multiple businesses while also raising their children and working to "advance substantive policies that will dramatically improve U.S. law in favor of all women, parents and children." We can't help but agree with Jared. The mother of his children is most definitely a force to be reckoned with!

9 Jason Sudeikis: "It's gonna be easy for him to grow up in a house of love and respect."

Jason Sudeikis and Olivia Wilde are the parents of two simply adorable little ones. When Wilde was expecting their second child, a daughter named Daisy, the SNL alum opened up to PEOPLE about his stunning fiance and what a wonderful mother she was to their then 2-year-old son Otis.

He told the mag that the key to being a successful parent was, "Just doing it with the right person.” He then gushed, "When I look at Olivia and the way that she pulls off all these things — it’s gonna be easy for him to grow up in a house of love and respect because I feel that way about his mom...It really is. I think that that’s ... probably what I’m most proud of."

8 David Beckham: "These little ones have the most amazing mummy."

Victoria and David Beckham are an undeniably posh power couple. They turn heads everywhere they go, and their four children are just as stylish, effortlessly cool and talented as their mom and dad.

The Beckhams have been together for nearly two decades: no small feat for a celebrity couple. It's likely that one of the things keeping their relationship strong is the respect and admiration they have for one other. On Mother's Day of 2015, David wrote on Instagram, "17 years ago our brood started and these little ones have the most amazing mummy that they love so much ... And I love her for many reasons but the main one is because she gave me the most amazing children."

Speaking about how he and Victoria have kept their relationship strong for so many years, the soccer star told BBC Radio 4's Desert Island Discs, "We’re a strong family unit. We’ve got strong parents. We were brought up with the right values.”

PEOPLE magazine's Sexiest Man Alive has also shared, "We know each other better than anybody. People have talked about, ‘Do we stay together because it’s a brand?’ Of course not. We stay together because we love each other, because we have four amazing children. Do you go through tough times? Of course. That’s part of relationships. It’s part of marriages. It’s part of having children. It’s part of having responsibilities.”

7 Prince William: "I am very proud of her."

Prince William and Duchess of Cambridge Catherine Middleton have three beautiful children together: George, Charlotte and their newest addition, Louis. Kate has her hands full raising three little ones while also fulfilling all of her royal duties. Luckily, her husband is nothing but supportive.

Wills recently gushed about the mother of his children in the ITV documentary When Ant and Dec Met the Prince: 40 Years of the Prince's Trust. He revealed, "Catherine has been doing an amazing job as a mother, and I am very proud of her."

Speaking about the way he and Kate have chosen to parent their children, William told CALMzine, "Catherine and I are clear that we want both George and Charlotte to grow up feeling able to talk about their emotions and feelings. Over the past year we have visited a number of schools together where we have been amazed listening to children talk about some quite difficult subjects in a clear and emotionally articulate way, something most adults would struggle with."

After Charlotte arrived, William told the BBC, "It has been fantastic and she has been a little joy of heaven. But at the same time it is more responsibility, looking after two little ones, especially when George is around. He's a little monkey. It is fantastic having a lovely little family, and I am so thrilled."

6 Hugh Jackman: "She does it all."

Hugh Jackman and his wife of over 20 years, Deborra-Lee Furness, have two adopted children together. Their son, Oscar, and daughter, Ava, are their pride and joy, and Jackman has been sure to let the world know what a wonderful mother his sweetheart is.

In an interview with YourTango, he said of his wife, "She's the greatest. I'm one of the lucky ones. She's very wise, a great actress, and a great wife and mother. Did you see her host 'The View?' She does it all. I'm really proud of her." 

There is no doubt about the fact that the Greatest Showman star is head-over-heels for his partner in crime. On The Ellen Degeneres Show, he said of his wife, "She's the greatest thing that ever happened to me and it gets better and better. And I'm kind of really grateful that I met [her] before anything kind of happened because everything that's happened in my career and on screen, off screen—we've always done it together."

Speaking about the challenges he and Furness faced while struggling with infertility issues, the actor has revealed, "It was painful. It's not easy. You put a lot of time and effort into it, so it's emotional." We are so glad Hugh and his beautiful bride were able to adopt the children they had longed for for so long, and we're happy to report that it seems their family is currently living happily ever after.

5 Tim McGraw: "It's a pretty cool thing for those girls to have her."

Tim McGraw and Faith Hill are one of those couples we can't help but envy. They have it all: good looks, great singing voices, beautiful children and each other. The pair has been together for over 20 years, but their love for each other doesn't seem to have faded one bit. In fact, it appears that their adoration for each other just gets greater with every passing day.

Speaking about the mother of his children, the country crooner teared up when he shared on Oprah's Master Class, "The chances that we’ve gotten to tour together, sing together, I mean, how many people get to do that in their lives? I think about the fact that we’re married and the fact that we raised these three beautiful daughters. And then I think about having three daughters and having [Hill] for their mom. It’s a pretty cool thing for those girls to have her.”

In an interview with E! News, McGraw shared of his relationship, "We just think about how much we love our family, how much we love our life together, growing old together, once your kids grow up. We feel pretty happy in the life that we've built together and the community we live in and the way we live our lives."

4 Channing Tatum: "She's a warrior."

Channing Tatum and Jenna Dewan recently announced the heartbreaking news that they are getting a divorce. Their fans were left reeling after they discovered that this beloved celebrity couple was no longer together, but Tatum and Dewan's split doesn't change the fact that Channing has said some pretty adorable things about his former flame over the years.

Soon after Dewan gave birth to Everly, the daughter they share, Tatum opened up to Vanity Fair about what it was like to watch his wife bring a child into the world. He gushed, "It was crazy. You feel helpless. We like to think of ourselves as big, strong men, and we could handle whatever situation. And reality is [that women] are so much stronger than we could ever be."

The Logan Lucky star continued, "There's a reason why we weren't given that job, evolutionary or whatever. My wife, she's a warrior. She did it as natural as you can. [As a man], you're basically a cheerleader. 'Come on, baby. You can do it.' I would've tapped out in the first." These two may have chosen to part ways, but the sweet things Tatum said while they were together will go down in history as quite possibly the most enchanting and romantic things a man has ever said about his baby mama.

3 Brad Pitt: "She has an incredible knack for inventing crazy experiences for them."

Brad Pitt and Angelina Jolie are sadly no longer together, but this doesn't change the fact that Pitt has said some absolutely swoon-worthy things about his ex wife and her mothering skills.

He once gushed to WSJ magazine, "When Angie has a day off, the first thing she does is get up and take the kids out. This is the most important 'to do' of the day. No matter how tired she might be, she plans outings for each and all. She has an incredible knack for inventing crazy experiences for them, something new, something fresh. I may be the bigger goof of the pair, but she invents the stage."

Brad has also dished, "Not a lot of people get to see a movie where their parents fell in love. What’s going to be funny is when they think Mom and Dad are a little bit cool. Because right now, we’re not cool Mom and Dad."

Brangelina may no longer be an item, but Pitt has assured the public that he doesn't regret his decision to make Angie the mother of his children. He has shared, "One of the greatest, smartest things I ever did was give my kids Angie as their mom.”

2 Dax Shepard: "The world's most thoughtful, nurturing, talented, determined woman."

Kristen Bell and Dax Shepard are the fun, quirky parents of two lovely little ones. They began dating in 2007 and got engaged in 2010, but they held off on tying the knot until same-sex marriage became legal in their home state of California. They wed in 2013 and have since had two beautiful daughters: Lincoln and Delta. The girls are kept largely out of the spotlight, and off of the couple's social media accounts, but Shepard and Bell aren't shy about confessing to a few of their parenting faux pas.

After Bell revealed she and her man were caught in bed doing "it" by their tiny tots, Shepard cleared things up on Jimmy Kimmel Live!. He told the talk show host, “Okay, they didn’t walk in while I was, like, pounding mom. We put on the TV in the living room — we’re bad parents — and then we stole away for a minute, afternoon delight, but we were just under the sheets and they walked in. It was more just explaining why we’re taking, like, a nap in the afternoon while they were loose."

Shepard is aware that he lucked out when he landed Bell as the mother of his children. He has proclaimed, "If Brad Pitt gets Kristen Bell, it’s like, ‘Well, of course he did,’ ...With me, it should be, ‘Oh good, a normal-looking guy got her. Maybe I’ll get me a Kristen Bell.’ But guys hate my guts for always dating women I have no right to be with."

The Chips actor has also shared, "I probably should have gone to jail at some points in time, but I didn't, somehow ... I have a whole system that works for me, and that's part of my worldview now. It's how I think of the world and how Kristen and I communicate. We don't let resentments fester. We just get it out and handle it and keep going."

1 Tom Hanks: "I'm the luckiest man alive."

Tom Hanks and his wife of nearly three decades, Rita Wilson, are one of the most solid couples in Hollywood. Hanks has made it clear that parenting is hard work, but sharing the experience with someone you love, respect and like to be around can make the job a lot less taxing. Luckily for him, he met his perfect match in Wilson and has been enjoying life with his love since they wed in 1988.

The A-list actor has two children, Elizabeth and Colin, from his first marriage, and shares two sons, Truman and Chet, with Wilson. According to Hanks, Rita is a wonderful role model and mother. He has shared, "We’ve been married for 25 years and it seems like we’ve been married 2-and-a-half to me, it’s blown by so quick. And we have two more kids and four of them all together and I tell you every day is fun."

Speaking about his marriage to Wilson, Hanks has also stated, "They say it must be hard work. No it's not. Every now and again you know, you gotta get over some stuff, but life is one damn thing after another, and its actually more pleasant to be able to go home with someone you like to spend time with in order to get with it."
