Kay Cola has claimed that she heard Chris Brown hitting Karrueche Tran back when the stars were dating.

Cola, 31, make her accusations on Twitter. The Grammy-nominated singer said she lived underneath Brown at the time and was so worried she even called the police.

The singer’s tweets came just hours after it was revealed that Karrueche was granted a temporary domestic violence restraining order against the rapper after he allegedly threatened to kill her.

In the filing, Tran had said that Brown had beaten her during their relationship.

Kay wrote: ‘Some of y’all make me sick to my stomach talking about. Karrueche lying. I’ve heard him beating her myself. I even called the police.

‘I used to cry over that situation hearing her screaming at the top of her lungs because I am also a victim of domestic violence.’
