Chris Brown sweats cigarette rihanna smoking

On Wednesday night Chris Brown got scolded by police for blocking traffic outside of a Hollywood nightclub, and that was after he lashed out at a valet attendant at a charity event in Studio City!

So what did the 23-year-old R&B bad boy do on Thursday? At first we thought he was going to lay low at home, but after lounging around in a pair of sexy yellow sweats, he decided to race around town in his red Dodge Viper and stop by the recording studio.

We love the fact that he gave us a smile and a wave from the driver's seat, but we're definitely not digging the cigarette he's puffing on -- that can't be good for his voice, and while Rihanna is open about her love for pot, we don't know that she's a fan of this kind of smoker's breath!
