PARTY PIX - Chris Brown Celebrates Release From Jail At Crazy House Party

Chris Brown's a free man now, and he celebrated his release from jail last night with girlfriend Karrueche Tran, his friends and a whole buncha red Solo cups at a Beverly Hills house party.

After just more than three weeks in the slammer in D.C., Chris has obviously put on a few pounds and let his hair grow a little. After tweeting to his 13.5 million followers, "Humbled and Blessed," and "Back to the Music and the Fans," Brown officially ended his relatively short stay of a 131-day jail sentence on Monday.

It's not all fun and games for Chris now that he's out, though -- he has to complete around 800 hours of a mandated 1000 of community service for his probation of violation stemming from his assault on Rihanna.

Chris' troubles ain't over yet!
