Despite her recent legal troubles, Nicole Richie has found something to smile about. According to an insider, during Nicole's July 25 trip to Cedars-Sinai Medical Center in LA, she underwent a very enlightening ultrasound. She and her boyfriend, Joel Madden, found out the gender of their baby: It's a boy! Although friends say the Simple Life star was hoping to have a girl, Nicole was very happy to get the news 16 weeks into her pregnancy. Now she has to get down to the not-so-simple task of picking out the perfect baby name.
