In September, Mars was busted at the Hard Rock Hotel in Las Vegas on suspicion of narcotics possession. The "Grenade" singer, born Peter Hernandez, had 2.6 grams of a substance believed to be cocaine.
Next up for Mars is a court appearance on February 4 when he'll enter his guilty plea. He'll be fined $2,000, sentenced to a year of informal probation, 200 hours of community service and drug counseling. After completing the terms, the first-time offender's record will be wiped clean.
