If you enjoy celebrity gossip, then you probably love your celebrity baby bump sightings, just like the rest of us. We love to obsess over celebrities' maternity styles, their first baby bump photos on Instagram, and the first baby photos to appear in magazines. But what about when those sweet little babies grow up to be sassy tots and saucy teenagers? Keep reading to find out what some of your favorite, famous little ones have been up to lately!

15 North and Saint West

North West celebrated her first birthday with a Coachella-themed Kidchella. Her second birthday was Minnie Mouse-themed. The little girl recently celebrated her third birthday as a Disney princess at Disneyland in Anaheim, California. Like lots of little kids, North now wants a puppy! The kid has everything else but mom Kim Kardashian West is trying to hold off on buying a puppy for as long as possible.

Aside from Kardashian West's social media feed, Saint West made his first public appearance in May when the Kardashians traveled to Cuba. The entire Kardashian clan vacationed in Cuba and filmed scenes for Keeping up with the Kardashians on the E! Network.

Cuba's not the only place the Kardashian kids have traveled. At only three-years-old, North West has already traveled to more places than most of us will ever get to go to in our lifetime! The beach village of Punta Mita, Mexico...New York and Paris Fashion Weeks...photo shoots and wardrobe fittings for Vogue magazine...just another day in the life of a globetrotting celebrity tot.

14 Sasha and Malia Obama

First daughters Sasha and Malia Obama have grown up right before America's eyes. When President Obama first took office, Malia was 10 and Sasha was 7. The oldest Obama daughter recently turned 18 and she's definitely not a little girl anymore. Although she's taking a gap year, the teen will follow in her parents' footsteps and attend Harvard University in the fall of 2017.

President Obama threw journalists into a tizzy at a recent speech with candidate Hillary Clinton when he mentioned daughter Sasha's presence on Twitter. The White House hasn't provided any information on whether or not the younger Obama daughter has a Twitter account but you can bet people have been on the hunt for it.

Aside from growing up in the White House (and, you know, traveling all over the place and meeting different world leaders) Sasha and Malia Obama have had a pretty regular childhood. They attend church services with their parents, take cell phone selfies, and dad even drops them off at school!

13 Kingston, Zuma, and Apollo Rossdale

Not only is she a singer, a fashion icon, and a former judge on NBC's The Voice, the gorgeous Gwen Stefani is also an awesome mom to three adorable boys: Kingston, Zuma, and Apollo. Although Stefani recently split from husband Gavin Rossdale, she has found happiness with fellow The Voice judge Blake Shelton, and tapped into her personal experiences with her new album. Although the album alludes to her emotional divorce from Rossdale and the blossoming romance with Shelton, she puts her three boys first and often tries to keep details of her personal life private. One thing that she has said publicly, however, is that she intends on keeping her split with Rossdale amicable for the kids' sake.

Stefani recently appeared on Chelsea Handler's Netflix series and discussed her relationship with Blake Shelton. She also discussed going on tour this summer, taking the boys on the road with her, and making stops and visits with them around the country.

12 Suri Cruise

Can you believe Suri Cruise is ten years old already? The little girl (whose custom wardrobe was once rumored to have cost around $3 million!) celebrated her 10th birthday at Tavern on the Green in NYC with mom Katie Holmes. A few months earlier, the mother-daughter duo got to hang out behind the scenes with the cast of School of Rock on Broadway.

And in December, the pair hung out with another famous mother and daughter, Hillary and Chelsea Clinton. Chelsea Clinton and actress Drew Barrymore co-hosted a holiday fundraiser for the Clinton campaign. Chelsea Clinton has a daughter, Charlotte, and recently gave birth to son Aidan in June. Barrymore has two little girls, Olive, and Frankie.

11 Jaden, Willow, and Trey Smith

Will Smith and wife Jada Pinkett-Smith have three kids: Trey, Jaden, and Willow. Jaden recently turned 18. He's been a busy kid, starring in The Karate Kid and modeling for Louis Vuitton. He tweets frequently and shares his opinions on current events and challenges social norms. He's not afraid to don a skirt or a dress, sending a message to teens that it's okay to be unique, and hoping that in a few years, kids won't be bullied or made fun of for their sense of style or their lifestyle.

At only 15-years-old, Willow Smith was recently named an ambassador for Chanel, making her debut in the label's fall eyewear campaign. She recognizes the importance of the diversity her addition to the label's roster suggests, and is proud to be a face of the label alongside actress Blake Lively and Kristen Stewart. The fashion-icon-to-be also graced the cover of Teen Vogue.

And then there's the son we don't often hear about; Trey Smith is Will's oldest son with former wife Sheree Zampino. The 23-year-old was a star football player in school but declined a college scholarship to instead follow in his father's musical footsteps. He's released several songs and DJs under the name AcE.

10 Blue Ivy Carter

They grow up so fast! Blue Ivy Carter, daughter of hip-hop power couple Beyonce and Jay-Z, turned four this year. She celebrated with a magical fairy princess birthday party. Blue Ivy has made out on birthdays before. What little girl doesn't want a pony? On her second birthday, Blue Ivy didn't just receive any old horse; Jay-Z bought her a full-blooded Arabian horse. And of course, every little girl wants to play with Barbies, right? Blue Ivy's diamond-encrusted Barbie doll cost $80,000. But what do you expect from the baby who took her first baths in a $5,200 Swarovski crystal-encrusted bathtub?

Beyonce and Jay-Z were once pretty protective of Blue Ivy but recently she's made appearances at the Super Bowl and the Council of Fashion Designers of America awards, where Beyonce was honored with the Fashion Icon Award last month. Although it was her mother that was receiving an award, Blue Ivy walked the red carpet with her father, posed for pictures, and waved to fans.

9 Brooklyn, Romeo, Cruz, and Harper Beckham

David and Victoria Beckham really like to party. They built a $187,000 playhouse for son Brooklyn's 6th birthday. (The boys also have a $50,000 custom-built tree house.) For Romeo's 10th birthday, they had a special performance from the band The Wanted. And for Harper's first birthday, they threw a $100,000 bash for the little girl that included ponies and pink bunnies. The little girl also received a $1 million painting for her bedroom.

Harper's not the only one with a decked-out bedroom. Do you remember those plastic glow-in-the-dark decals that you could stick on your ceiling so that you could sleep under the night sky? Brooklyn's bedroom was decorated with a $50,000 fiber optic ceiling that simulates a starry sky.

In addition to all of the fancy gifts and lavish parties, fashion shows, and social media attention, the kids also all received David and Victoria's good looks. All four kids are stunners!

8 Pitt-Jolie Kids

Angelina Jolie and Brad Pitt are well-known for their large family. In addition to adopting kids from Vietnam, Cambodia, Ethiopia, and Namibia, the couple also has two biological children.

Jolie, the actress-turned-activist, has influenced her kids' humanitarian efforts. Daughters Shiloh and Zahara recently offered to help sponsor a Cambodian family with thirteen children. The Jolie-Pitt girls took the kids out to buy new clothes and bicycles.

While the family is probably used to the crowds going wild for their appearances on the red carpet, it must be pretty crazy to be trailed by paparazzi and photographed for doing normal things like playing in the park or taking the kids to the grocery store.

7 Louis and Laila Bullock

Sandra Bullock is one of America's highest-paid actresses, and was named People Magazine's Most Beautiful Woman of 2015. She adopted two children from Louisiana's foster-care system: son Louis in 2010 and daughter Laila in 2015.

Louis is the proud owner of a $14,000 Andy Warhol painting. That's nothing, though. On the Today Show in 2011, Bullock joked about going crazy with her holiday shopping, admitting that she bought the boy a plane.

Despite the private jet, Bullock sounds like a really down to earth mom. Louis and Laila share a room. After each kid is tucked in, she reads to them. She said she feels successful when she knows each kid is fast asleep, knowing that they made it through another busy day. Doesn't every mom feel like that when her kids are in bed?

6 Emme & Max Anthony

When your, "Welcome to the World" party, is thrown by your godfather Tom Cruise, of course it's going to be a lavish affair--an $200,000 affair, to be exact. When Jennifer Lopez and Marc Anthony's kids were born in 2008, they had an entire wing of the house to themselves, 600-thread count crib sheets, and diamond-encrusted rattles. (Oops--almost forgot that each baby got their own Shetland pony, too!)

The twins turned eight this year, and J-Lo celebrated by taking them to Disneyland for the day. While Lopez, boyfriend Casper Smart, and Max dressed casually, Emme donned a princess outfit to stroll around the park. She talked about the trip on Late Night with Seth Meyers saying that she got extremely emotional on this birthday because her kids weren't her little babies anymore.

5 Trump Kids

Donald Trump has been making headlines daily as he continues his 2016 presidential campaign. We're familiar with his daughter Ivanka but he also has another daughter, Tiffany, and three sons, Donald Jr., Eric, and Barron. Eric Trump launched Trump Winery in Virginia in 2011. Ivanka dabbles in fashion.

The youngest Trump son, Barron, age 10, is growing up to enjoy the finer things in life. He dresses in suits like his father, prefers everything in his bedroom to be clean and white, and once used mom Melania's caviar-based skincare line every day to keep his young skin moisturized.

4 The Combs Kids

You might not know who Justin or Christian Combs are but you've probably heard of his dad--Sean Combs, aka Diddy aka Puffy aka Puff Daddy. For Justin's 16th birthday in 2010, the rapper and fashion mogul gave his oldest son a $360,000 Maybach! (And a driver.) For Christian's 16th birthday in 2014, Combs planned a star-studded bash complete with swag bags as party favors.

Diddy is daddy to six kids: another boy (Quincy) and three girls (D'Lila, Chance, and Jessie.) With the collaboration of his three daughters, he recently added a girl's clothing line to the Sean John clothing brand.

3 Madonna's Kids

With her custody battle with ex-husband Guy Ritchie now behind her, the Material Girl and her four children are off to Malawi. Madonna adopted her two youngest kids, Mercy James and David Banda from Malawi and tries to go back and visit the country often.

Lourdes, or Lola, just wrapped up her sophomore year at the University of Michigan, where her mom attended. In addition to studying musical theater, the teen recently became one of the faces of Stella McCartney's Pop perfume. Lola bears a striking resemblance to her superstar mom.

Younger brother, Rocco, who is 17, was reunited with Madge in June after the custody dispute with Ritchie. He originally claimed that he was tired of Madonna's strict parenting ways and would prefer to live in London with Ritchie. Since the dispute, the family seems to have worked everything out.

2 Neil Patrick Harris' and David Burtka's Twins

Neil Patrick Harris seems like the type of guy who can do everything: sing, dance, act, magic tricks! He also appears to be a sweet, doting dad, as well! He has two children, Harper and Gideon, with actor David Burtka. The twins were born via surrogate. Burtka revealed to Wendy Williams last year that the twins' distinct personalities made it clear to him which kid was biologically linked to which partner.

In addition to their lively personalities, Harper and Gideon are just as cute as can be; NPH and Burtka frequently share family photos on Instagram. The dads have shared photos of everything from awesome homemade birthday cakes to the annual family Halloween costumes like the cast from Star Wars, the Wizard of Oz, Alice in Wonderland, and Batman. These guys are definitely up for Dads of the Year!

1 Prince George & Princess Charlotte

First, we swooned over Prince William and Kate Middleton's wedding. Then, we bump-watched and waited for news of Prince George's arrival, oohing and ahhing over how breathtaking Kate looked as the Royal Family appeared outside of the hospital to reveal their little one to the world. Now their family has been blessed with the addition of Princess Charlotte, and the royal kids are as adorable as can be!

The prince and princess have been the recipients of many gifts from family, fans, and world leaders. Shopping for a baby shower or baby's first birthday can be hard enough but what do you get for a royal baby? A gift card probably won't cut it, huh? Well, how about some (very expensive!) rattles? On her first birthday, Charlotte received a silver rattle and a white gold rattle studded with diamonds, rubies, and sapphires, estimated to have cost around $44,000!

Despite being showered with fancy gifts, George and Charlotte have an almost normal childhood. Kate prefers to cook dinner and the family eats together at home. The Prince and Duchess also switch of bathtime and bedtime duties, unless they are away on royal business. Although Prince William has sometimes been criticized for not making many public appearances, he chalks it up to being a father, and putting his family first; as it should be.
