Kimora Lee Simmons' publicist says the model and "Kimora: Life in the Fab Lane" reality show star has given birth to a son in Los Angeles. The child was born Saturday and is the first for Simmons -- the ex-wife of hip-hop mogul Russell Simmons -- and her current beau, film actor Djimon Hounsou. The newborn's name had not yet been publicly announced. "Kimora and Djimon are the proud parents of a new baby boy. Both mother and child are doing great," Simmons' representative told TV's "Access Hollywood." Simmons also has two daughters with her ex-husband.
