Karruche Tran Hooray Henry's Chris Brown Rihanna jail

Guess she has something to smile about!

After news broke yesterday on Chris Brown being arrested for violating his probation, his ex-girlfriend Karrueche Tran kept things moving as she was out and about in Hollywood.

The much maligned singer's former flame looked hot while at a Children's Hospital charity event and Hooray Henry's later in the night.

Looks like she's doing just fine post-CB!
