And the fallout continues: After allegedly attacking girlfriend Rihanna, R&B star Chris Brown may have more than a court date to worry about. Sources told Us Weekly that hip hop impresario and "99 Problems" Jay-Z "hit the roof" when he learned of Rihanna's alleged injuries, and that "Chris is a walking dead man. He messed with the wrong crew" reports the New York Post. The mogul discovered and mentored the "Umbrella" singer who was said to have contusions to her face, a cut lip, bloody nose, and bite marks after an argument was sparked the night before the Grammys ceremony. Brown is currently released on $50,000 bail.
