Pregnant actresses, musicians, singers, models, athletes and other stars at Celebrity Pregnancy .com

Ok, really. How do the stars do it? It seems that every new mom in Hollywood pops out a baby and then is snapped out and about a week or a month later looking like she never had a baby at all! The latest example of this phenom?

New mom Sarah Michelle Prinze (aka Gellar)! She was seen out and about at the Anastasia Nail Salon in Beverly Hills on Friday looking as svelte as ever. Just a month after giving birth to daughter Charlotte Grace!

There has been no official word as to how Sarah Michelle did it, but she did stay true to a workout regime during her pregnancy. She did 55-minute Pilates sessions up to three times a week with trainer Alycea Ungaro.

She looks great!

Model Heidi Klum is expecting her fourth child - a baby girl - any day now, and since this is her fourth pregnancy, she has learned a few things along the way. Like how to dress, for example. Donning a dynamic black, form-fitting Marchesa gown for the Emmy’s earlier this month, Heidi proved that pregnancy is sexy!!

She told UsWeekly magazine at the event, “When you’re this far along, I feel like if you wear a big tent, you look even bigger than you are. So it’s nice [to wear something] tighter.”

Regarding baby-on-the-way, Heidi said, “We’re ready.” But one thing they haven’t finalized? A name.

She and hubby Seal are going to wait to meet their baby girl, she revealed.

Last Tuesday in Las Vegas, actress, model mom and now entrepreneur Ali Landry introduced her new baby — her children’s clothing line, Belle Parish.

“Belle Parish is classic, sweet, whimsical clothes that are rooted in our Southern upbringing,” Ali told PEOPLE of the line she’s launched with partner Annie Kate Pons.

“For us, it’s like the hometown department store that closed 60 years ago and the doors have just re-opened. It’s vintage and tradition with a modern twist.”

She added, “to see it come together is a miracle! Belle Parish is about creating a lifestyle, but because I’m a mom I wanted to start with kid’s clothing. I also have a strong point of view about dressing children in age-appropriate clothes. I want to celebrate each stage of their life. We’re so excited about people’s response to our ideas.”

What do you think about the way children dress today?

On Tuesday’s episode of The Rachael Ray Show, musician-turned-actress Ashlee Simpson-Wentz spoke about her son (with hubby Pete Wentz) Bronz Mowgli, 9 1/2 months.

She told the host that little Bronx has quite the sense of humor. She said, “He cracks himself up all the time. Like, he’ll do something, and then he’ll start laughing. It’s cute. It’s very entertaining. He’s like, ‘I am so funny!’ And he probably gets that from me because I make jokes that are not funny, and I’m the only one laughing.”

She also admits that Bronx can be a bit of a flirt. “Everyone loves him, and he definitely thinks the girls are pretty. [He] kind of gives them the eye. He’s flirting already! Yes, I’m in trouble!”

Pregnant Tisha Campbell-Martin and hubby Duane Martin were showered by friends over the weekend at a French Cirque-du Bebe-themed baby shower in California.

Hosted by Jayneoni Moore, a friend of the family, the celebration for the Martin’s expected arrival - a baby boy! - was styled by Jennifer Sbranti of Hostess with the Mostess, who decorated the location with elephant vases, monkey statues, zebra-print tablecloths, crystals, and gigantic ostrich feature “trees” made up of more than 200 blue and yellow electric feathers.

Of the fete, Tisha said, “I was so surprised by everything and how extraordinary the party was. “I am such a control freak and usually plan my parties, but this was the most beautiful – from the people, to the decor, to the food.”
