Kimora Lee Simmons

Kimora Lee Simmons credits her post-baby weight loss to a very unique diet.

"I'm on the fabulosity diet!" the 36-year-old told Us Weekly. "I'm kind of perfecting it now. It's a little workout, a good diet. I try to cut out a little bit of the sweets and the junk, but I love that, so it's a little hard."

The model and former Baby Phat president is married to Djimon Hounsou, with whom she has a son 2-year-old son, Kenzo. Her other two children, Ming Lee and Aoki Lee, are from Simmons' previous marriage to Russell Simmons.

"I'm a mom first and I'm a business woman [second]," Simmons said. "I want girls to understand the difference between this and fantasy. . .It took me an hour to get ready, and I want girls to know, 'Take it easy! You're beautiful.' Size 2 is really unreal."
