PHAT BABY: It looks as though Kimora Lee Simmons is dabbling in maternity wear. The creative head at Baby Phat was seen lunching with beau Djimon Hounsou in Beverly Hills last week wearing a black T-shirt bearing the Baby Phat logo with an arrow pointing to her bump. To test the waters, Simmons will sell the T-shirt on her site, babyphat.com, retailing for $44. Her reasoning for the T? “To celebrate my phat bump and embrace my changing figure, as I believe all women should do,” Simmons told WWD. Simmons’ third child (her first with Hounsou), a boy, is due this summer.
