One of America's darlings is preggers. Hilary Duff is one of those sweet as sugar actresses that will forever be a tweeny girl in the minds of many. She made her fortune starring in the Disney giant, Lizzie McGuire and now, little Lizzie is all grown up and making some babies.

Motherhood is not new to Hilary, however. This is the lady's second rodeo when it comes to parenthood. Her son Luca, with her ex-hubby Mike Comrie, is now six years old. While this starlet is a seasoned professional when it comes to nighttime feedings, diaper changes and stroller pushing, plenty of things about this second baby will be new to the actress.

For starters, she has a new partner by her side. This second bundle of joy will also be Hilary's first little girl. She is also a full-fledged woman coming into her own.

At thirty years old, she is no longer "just a kid."

Congrats to Hilary, her new man and big brother Luca! Best of luck on your new and growing family. Here are twenty inspiring images of Ms. Duff rocking the heck out of pregnancy number two.

20 A Vision In Red

I try to create this hairstyle on myself at least twice a week and it never looks this fantastic, not by a long shot. Hilary is an absolute vision in red here as she flaunts her beautiful bump on the red carpet.

That is some serious pregnancy glow spreading across her lovely face! It isn't easy to look this fabulous when you are expecting, but Duff has a way of making those nine long months of gestation look effortless. Her stylist should get a raise for helping Hilary pull this look off. She is one smoking hot mama!

19 The New Baby Daddy

Miss Hilary Duff is patiently awaiting the birth of her second child, a little princess to join her gorgeous six-year-old son, Luca, with her new beau Matthew Koma. Koma is a musician and accomplished songwriter who has penned lyrics for Grammy-award winning band Zedd as well as numerous other artists.

Now, he is about to add first-time father to his list of achievements. Both Duff and Koma are over the moon about their little girl and have taken to their social media channels to express their excitement. We can't wait to see this beautiful family of four light up Instagram in the coming months.

18 Pregnancy Perfection

Welcome to the most majestic maternity shoot in all the land folks.

She just makes pregnancy look far too easy, doesn't she? Look at her sipping on her Welch's sparkling juice while she munches on goodies from her perfect picnic basket. This is a far cry from the rest of us who spent nine months ordering pizza and eating ice cream directly out of the tub.

She looks completely at ease and comfortable perched atop that rug. No way would I have been able to get back up off of the ground without serious assistance during my third trimester.

17 Multitasking Like A Boss

We can tell from this photo that Mama Hilary is a master multi-tasker. Just look at her carry her books, keys, a drink, and her purse while at the same time looking fresh and fashionable in that white ensemble.

It might be time for this Hollywood mommy to up her purse game and spring for a giant diaper bag though. When her little girl comes along, she is going to have to carry her around town as well!

It's good to see that she has the whole multi-tasking thing down to an art because as a mother of two, multi-tasking is an essential skill to have.

16 A Piece Of Pregnant Art

We aren't sure exactly how many maternity shoots Ms. Duff had done by now, but if we looked as good as her while expecting, we would make sure to load up on them too.

Here she is holding hands with her baby's father looking like a piece of art. I would seriously consider hanging this on my family room wall it's so perfect.

This makes me want to go back in time and redo everything I ever did during my pregnancies and do them all the "Hilary Duff way."

This girl knows how to take a picture, that's for sure.

15 Walking The Pups

Both Duff and Koma are huge canine lovers and they have been snapped using those pups of theirs to remain physically fit throughout Hilary's second pregnancy a few times.

Sadly Duff had a beloved furbaby pass away earlier this year, but she and her lover made some room in their home and their hearts for an old dog who needed a family to love. In March they took in a senior animal from the Love Leo Rescue Center, based out of Los Angeles.

The old lady, named Lucy, joined Duff, Koma, and one of the pair's resident dogs, Izzy, for a bit of fresh air and exercise. With two kids and four dogs running around, the couple's home is going to be very busy!

14 Slaying The Casual Look

Not every day in Tinseltown is a red carpet day and Hilary can go from getting all gussied up to throwing on a tye-dye sweatshirt and some boyfriend jeans while still looking cool.

Here she is doing a bit of grocery shopping in her comfy clothes. After all, she needs to feed that bump! The fact that she can step out in town and look so down to earth and fuss-free makes us moms desperately want to hang out with her.

Just think Hilary, we could rock our sweatshirts and jeans together while we browse the aisles of Target together!

13 Bump-Rocking Selfie

One thing we love about mama Hilary is that she rocks her body and loves her curves. After Hilary gave birth to her first son, she allowed her body to return to its pre-pregnancy state at its own rate.

She didn't starve herself and cave to the pressures of Hollywood, she instead chose to love her baby and her body, and it wasn't long before she got her groove back.

That "groove" helped her land a hot musician after the break up of her marriage. Judging from this bathroom selfie, Hilary Duff is still loving her body and having fun flaunting it.

12 Baby On Set!

Duff is exceptional for so many reasons, one of those being she was able to take her child acting career and channel it into a lucrative adult acting career. She now stars in the hit television show, Younger, (which is exceptionally good for those who have not seen it.)

Her character, Kelsey, is not expecting in the show, but Duff has a blossoming belly, so the writers and producers have had to do their best to keep her bump under wraps while filming.

Here she is on the show's film set. We spy a bump there Duff. This was taken in those final weeks of being able to mask the obvious.

11 Mommy Of Two

Even though a new baby is lighting up Hilary and Matthew's world right now, she still dotes on her firstborn son, Luca. Hilary became a mother to Luza Cruz in her early twenties when she married NHL player Mike Comrie, and the pair welcomes their son into the world together.

The marriage didn't last longer than six years, but the two continue to love and co-parent their child as best they can. Here we see Duff soaking up the sun and surf with her only kiddo before he officially becomes a big brother to a little sister. She seems to be enjoying those magical moments with her boy while she can.

10 Sister-Auntie

When Hilary gave birth to her first child, she was a bit of an island in the sea of parenting. Her sister Hailey had not et joined Club Mom six years ago, but these days Hailey is a well-established member of the coolest group in Hollywood.

Hailey has two children now and her second baby was recently born, so Hilary and Hailey's little ones will grow up very close in age. It has to be an incredibly cool experience to go through parenthood alongside your first, and best, friend.

We bet they are going to have a total blast hanging out with their tiny tots!

9 Practice Makes Perfect

It's been six years since Hilary has cuddled a bundle of joy that is all hers. Her son Luca is well out of diapers these days, and it might seem to Hilary that she is starting her parenting journey all over again.

Here she is getting in a bit of infant practice with her little niece, Lulu Gray. Hilary's older sister, Hailey Duff, gave birth to her second daughter on June 5th of this year.

Just think of all the cute, matching outfits Lulu and her younger cousin will be wearing once baby Duff arrives! It will be the second coming of good-looking Duff girls.

8 Over-The-Moon For Overalls

The fact that this heavily pregnant actress can look this good in denim overalls is beyond me. Grown women in one piece, jean apparel can go so utterly wrong, but somehow Hilary managed to make us all want to buy a pair of jean overalls from the nearest Old Navy store...and immediately get pregnant.

In one picture, Duff made us all want to wear an outfit made for toddlers and carry around forty pounds of excess weight in our mid-sections. That is the power of this pregnant lady's style, guys. She is well on her way to being a fashion icon for the expecting.

7 Soaking up the sun

This has certainly been the summer of bikinis for Hilary Duff. It is obvious to everyone who is following the star's pregnancy that she is in love with her blossoming body and is more than happy to sun her baby bump whenever she gets the chance to do so.

It's a great idea to soak up the last of the relaxing days Hilary. In a few short weeks, there will be no more lazy days by the pool as her days will be filled with feeding, changing burping and rocking all while caring for an active six-year-old boy.

6 Channeling Her Inner Mary-Kate Olsen

The fashion-forward mama is channeling her inner Mary-Kate Olsen here with her leather jacket, red bag, and messy hairstyle.

We have to be honest, we love this look. While Duff typically goes for the fresh-faced bohemian look, this edgy get up is seriously working for her.

It screams, "I am pregnant, it's summer, don't mess with me." How she isn't melting underneath that heavy coat is beyond me. I remember being a sweaty pregnant mess back when I was expecting during the summer months. In fact, I was a hot sweaty disaster during the cooler months too.

5 Flowy And Flawless

This is her trademark boho look, and she does it so perfectly. The pic was snapped as Duff was out in New York City on the evening of her television show Younger's finale.

She could wear a giant, paper sack and still look like a million bucks.

Many heavily pregnant women would look like large sea animals in a dark blue moo-moo dress, but not our pregnant muse Hilary.

Her tightly wound bun is always perfection, and this is yet another example of Hilary hair goals here folks. I'm trying not to be jealous right now, but it's so hard.

4 Still Has That Sense Of Humor!

Duff is undoubtedly getting uncomfortable in her pregnancy at this point. When women near the end of the forty week mark, things start getting cramped in the belly. Lying down and finding a comfortable position to rest in is nearly impossible for heavily pregnant women, but not for their little furry friends.

Hilary manages to find the humor in the fact that she can't seem to get cozy, but her little puppy pal does just fine in creating a makeshift pillow out of her round belly. At least someone is getting a nice nap in, too bad it isn't the mama!

3 A family affair

It's nice to see Hilary and Matthew spending some time with little Luca before his baby sister makes her debut. Welcoming a new baby after being an only child for six long years can't be an easy adjustment for any child.

We would imagine that this event might be even more challenging for a youngster whose mother lives her life in the public eye. Throw in a new "father-figure" and a blended family, and you could have a real mess on your hands.

From the look of it, Duff and Koma are doing a bang up job at making sure Luca feels just as important and loved as ever!

2 Chic As Ever

There she goes again with her on-trend look. This image makes me feel kind of bad for spending nine months of pregnancy in my husband's sweatpants and baggy sweatshirts.

The chunky scarf and the boots do an excellent job at making black stretch pants look fancy. It isn't easy to turn leggings into something that people actually want to look at. But our Hilary figured out a way to make them alluring, all while growing a belly full of baby.

Also, no one does a messy bun like this girl. Her daughter is going to be the chicest infant on the block.

1 Congrats Lovebirds

It's safe to say that baby girl Duff is about to be surrounded by a whole lot of love. Her parents are clearly smitten with one another and will surely be just as smitten with their bundle of joy once she arrives. Very soon now musician Matthew Koma will not only have a beautiful girlfriend to shower with affection and admiration, but also his first-born child and daughter to love and adore. Congrats to these two beautiful human beings on their new addition to the family. We can't wait to see the tiny sweetheart you guys! We are sure she will be perfection.
