CHRIS BROWN is the father of a 9-month-old baby girl, if we're to believe TMZ. They say the girl's mother is a 31-year-old former model named Nia, and one source claims she's one of RIHANNA's friends. She and Chris have known each other for several years, but they're not together. And Chris is supposedly happy that he's a dad. He's 25, by the way. (Here's a picture of the baby.) No word if it happened during one of Chris' many breaks from his on-again off-again girlfriend KARRUECHE TRAN.
