Pop singer Bruno Mars has pleaded guilty to possession of cocaine as part of a plea deal that could remove the conviction from Mars' record. After Mars, real name Peter Hernandez, entered his plea, a Clark County judge sentenced him to probation and a $2,000 fine. As part of his probation, Mars will have to undergo drug counseling and perform 200 hours of community service. If Mars completes the probation and stays out of trouble for the next year, the judge could dismiss the conviction. Mars was found with 2.6 grams of cocaine upon being arrested in a casino bathroom after a nightclub performance in September.
