Katherine Heigl

Nicole Richie

She went from almost skeletal-skinny to sexy mama, resplendent in her maternity curves. We can’t imagine this has gone unnoticed by Joel Madden, who asked the reformed party girl to marry him after two kids (and a couple of needed pounds).

Nicole Kidman

Before? Criticized for her line-free forehead as often as she was praised for her cutting-edge acting chops. But after giving birth to her daughter Sunday, she’s been flaunting a softer look that’s anything but frigid.

Ellen Pompeo

Her post-baby perma-smile is making her look like just a girl herself. Maybe she’s trying to put what she told Self into action: “I hope Stella has more self-confidence than I did as a child. Because when you believe in yourself … you don’t look for validation from others.”

Ashlee Simpson

This former tween actress-turned-singer seemed to go from girl to woman overnight after the birth of son, Bronx. She shed the punk hairstyles, clothes and boyfriends, and found the look that suited her best: proud mom and wife.

Jennifer Hudson

The Oscar-winner announced to Good Morning America that her recent weight loss was all about her first-time venture into motherhood: “I have a child now and I want to set a great example for him.” And she sure looks fab while doing it!

Angelina Jolie

She went from a blood-necklace-wearing goth to St. John’s couture spokesperson. And Brad Pitt isn’t a bad everyday accessory, either.

Jessica Alba

Pre-Honor, Alba rarely smiled in public (when she wasn't on the red carpet.) These days, paparazzi catch that mega-watt grin every time her daughter does something adorable, which is, obviously, all the time.

Sheryl Crow

As a rock and roller she was tough and sexy, but as an adoptive mom (and cancer survivor) she brings new meaning to the word strong. Now that her son Wyatt has a new brother, Levi James, we bet she’ll continue to prove you don’t have to give birth to get that new-mom glow.

Katherine Heigl

Even though this new adoptive mother is probably exhausted, she also looks younger than ever. Heigl has said she's quit smoking to be a better mom — and her looks seem to be thanking her!

Katie Holmes

Suri’s mom caught a lot of flack for going from Little Miss Dawson’s Creek to Mrs. Tom Cruise in a xeno-second, but you have to hand it to her — from boyfriend jeans to her modern bob, she’s become a style icon. Perhaps it has something to do with rubbing shoulders with another fashion-forward Hollywood mom, Victoria Beckham?

Heidi Klum

Sure, she’s a supermodel; she’s always looked great. But the reason Klum rounds out our list is because of the sheer volume of babies she’s given birth to and bounced back from. Her peace with a few extra pounds showed when she walked the Victoria’s Secret runway a few weeks after birth — and made us thankful we don’t have to do the same.
