At a party in L.A. for her Jovovich-Hawk clothing line, Milla Jovovich joked with photographers that she didn't want to turn to the side too much – but there was no hiding that fact that she's pregnant and loving it.
"I'm gaining weight, which is fun," the model-actress-designer, 31, who is expecting her first child
with fiancé Paul Anderson, told PEOPLE at the Monday night event hosted by Gen Art.
"I've been craving lots of bad stuff but I've been cooking a lot. I did this amazing slow-roasted tomato dip the other night, and steaks, and, oh, I've been eating my mom's potatoes – I know how to make my mom's potatoes – like crazy. It's awful. I have to stop."
And how is she preparing for motherhood? Jovovich says she's "just reading lots of books and trying to talk to all my friends who have kids and getting prepared to start my prenatal yoga and all that kind of stuff soon."
She's even getting a little bit ahead of herself: "I've read a couple of books by Harvey Karp, the pediatrician, and of course I've got Coping with Preschool Panic
[a guide to Los Angeles private preschools]. I'm like four months pregnant and I'm already coping with preschool panic!"
But for now, the Jovovich-Hawk clothing line, which she cofounded with Carmen Hawk in 2003, is taking up most of her time. "Carmen and I have been friends for 13 years, so it's really fun for us to do these amazing, character-driven collections together," she said. Their latest is "very 60's cocktail party-Sharon Tate-Valley of the Dolls
meets Blondie. It's very cool."
And unlike other celebrities-turned-designers, she's hands-on. "We're not coming in with a design team going, 'Yes, yes, no,' " she said. "We're drawing it, picking out fabrics, ordering stuff and making sure it comes in on time. It's a lot of work."
But the real question is, will she design maternity clothes? "I have some great ideas," she said, "but no, not yet."
