Wiz Khalifa and Amber Rose's impending divorce might get ugly now that he plans to fight for custody of their son Sebastian. Now the rapper is denying that he cheated on Rose.

Insiders close to Khalifa have told TMZ that the 'We Dem Boyz' rapper had been separated from Rose for weeks. "I just didn't want to be married to her anymore," he reportedly told friends.
