When we interviewed Bruno Mars last month and asked the 23-year-old hitmaker if he had any crazy Vegas stories he’d like to share, his response was, “Yeah, I don’t wanna talk about that.” He was joking, but his arrest at 2:40 a.m. on Sunday in Sin City was no laughing matter—cops nabbed Bruo (real name: Peter Hernandez) at the Las Vegas Hard Rock Hotel  & Casino after he was allegedly found to be in possession of narcotics by security guards.

The singer had performed at the Hard Rock on Saturday evening. Meanwhile, Mars has yet to acknowledge his arrest. He tweeted the following early this morning:

“Texas is dope! Im in dallas rite now looking foward to meeting some folks @ the radio stations. tune in for a special live performance”

UPDATE: TMZ is now reporting that Mars was busted for being in possession of 2.6 grams of cocaine on Sunday. Expensive habit, Bruno—and clearly not worth it. Rap-Up.com posted the above mug shot this afternoon.

Mars’ debut album Doo-Wops & Hooligans is due out October 5. His debut solo single, “Just The Way You Are”, is currently #3 on the Billboard Hot 100.
