Chris Brown announces he's single again, Karrueche mocks him on Twitter

Guess the Sevyn Streeter story is true, even though Chris Brown went on record to deny he slept with her, describing her as a sister. OK, Chris, we hear you! Anyway, Chris blacked out on Karrueche last night at the Power 106 Cali Christmas concert in LA. He told the audience that he was a single man again. He said..."Ladies scream if you're single...well I'm single too. F*ck that b*tch." lol

A few hours later Karrueche tweeted mocking Chris (above). We all know its a matter of time before they get back together. See the Chris Brown video after the cut...
