Not that Chris Brown was peaceful before, but now he gets even more tense than before. The singer could face a possible criminal investigation. The reason is that he violated his probation after he went on a Los Angeles nightclub following his sentencing for beating up ex-girlfriend Rihanna. The singer broke up the rules of his probation because he is under 21, so not allowed to go into a night club. Note that he wasn’t too young to beat Rihanna.

On Tuesday, Chris Brown faced L.A. Superior Court and was given a five year probation order, as well as six months hard community labor due to his violent behavior against Rihanna this February.

But after that, the singer went out (to celebrate maybe) at West Hollywood hotspot Guys and Dolls even though he is still 20 years old. “It (breaking probation) won’t be taken lightly. If you break the law, you’re in trouble”, Los Angeles Probation Department spokeswoman Kari Webb declared for E! News.
