There's a chance he could go to jail for a probation violation, but that doesn't mean Chris Brown can't party it up in the meantime! Last night the R&B bad boy stopped by a club in Hollywood with pal Wale, and oddly enough, the boys weren't joined by any females.

The night before that, Rihanna arrived at Playhouse at 2:20am, which was just a few minutes after Karrueche Tran left the club with a male pal. Rihanna will be back in town for several weeks, Chris is single, Karrueche doesn't seem to mind the back and forth relationship with Chris and all three of them like to hit the clubs, so we're guessing there will be some sort of drama before the summer ends...

Looks like he had a good time though!
