VIDEO : Neighbor Insists She Often Heard Chris Brown Beat Karrueche Tran

Kay Cola, Chris Brown?s former neighbor, is backing Karrueche Tran?s claims that he was abusive during their relationship--while he was still on probation for assaulting Rihanna.
Just days after Tran was granted a restraining order against her ex after he allegedly threatened to kill her, neighbor Kay Cola opened up about the couple?s volatile romance.
Cola claims she previously heard Brown beating his then-girlfriend up from her own home, on numerous occasions.
According to Celebuzz, Cola tweeted that as a survivor of domestic violence herself, she called police on Brown.
