A source close to Chris Brown and Karrueche Tran told TMZ that Tran had no idea Brown had a baby. Even worse, she did not know that he was having an affair with her friend Nia Gonzalez, a former model. News broke last night that Brown, 25, had a 9-month-old baby girl with Gonzalez, 31. Gonzalez has been photographed with Tran before as they partied together. Sources told TMZ that Karrueche and Brown were not speaking after they argued last week, but he tried to reach out after the news broke and she allegedly did not respond. DNA tests proved last week that Brown is indeed the father of the baby, and Tran graciously bowed out. She wrote on Twitter, “Listen. One can only take so much. The best of luck to Chris and his family. No baby drama for me. “
