Bruno Mars has been formally charged with criminal possession of a controlled substance, a spokesperson for the Las Vegas district attorney’s office tells EW. Mars, whose smash “Just the Way You Are” is enjoying its second straight week as the biggest song in the country, was arrested early Sept. 19 after police allegedly found him with 2.6 grams of cocaine after a concert at the Hard Rock Hotel & Casino.

Mars is due back in court Nov. 18. If he is convicted, potential punishment for this charge could include one to four years in prison and/or a fine of up to $5,000 — but if the singer has no prior convictions, Nevada law dictates that any such sentence would be automatically suspended and he would be put on probation instead.

A spokesperson for Mars did not immediately reply to EW’s request for comment. UPDATE: Mars’ label, Elektra Records, has issued the following statement: “We congratulate Bruno Mars on his chart topping success, and provide him with our full love and support.”

The baby-faced Hawaiian singer-songwriter-­producer, 24, is all smiles in a white T-shirt, a varsity jacket, and his signature fedora. Posing for pictures with smitten admirers after the performance, he pauses only briefly when asked how he is feeling. “Look,” he says. “I’m happy now.”

Bruno Mars was arrested early Sunday morning in Las Vegas on suspicion of cocaine possession, according to police. While it was initially reported that the singer-songwriter-producer behind hits like “Nothin’ on You” and “Billionaire” had been busted with an unknown narcotic, a report issued this afternoon by the Las Vegas Metropolitan Police Department identifies the suspected substance.

Police say they were summoned to Las Vegas’ Hard Rock Casino at 1:50 A.M. on Sept. 19 “to investigate the report of a Latin male adult being detained by hotel security.” Mars, born Peter Hernandez, had performed at the venue hours earlier. Police say they found Mars with 2.6 grams of “‘white powdery substance’ believed to be cocaine.” He was booked and released at 7:45 A.M. the same day and has not yet been charged.

UPDATE: A spokesperson for the Clark County District Attorney’s office says that it will probably decide whether or not to proceed with criminal charges by the end of this week. If charges are filed, Mars will most likely be due to appear in court Nov. 18.

Reps for Mars have not yet commented on his arrest.
