Karrueche thrashes Chris Brown after arrest. Yup, they're broken up

Chris Brown's on-and-off again girlfriend Karrueche Tran trashed him on twitter today a few hours after it emerged that he'd been arrested for punching a man in D.C. Her reaction to the news came as a surprise to some people because their split, which happened recently, hadn't been made public.

Chris and Karrueche had a falling out about a week ago after she asked to move into Chris' LA pad. A source claims Chris flipped over the request and accused Karrueche of not being 'grateful' for everything he already does for her, and for trying to push him too hard. Chris and Karrueche  have since unfollowed each other on Twitter. Lol.
