"Billionaire" singer Bruno Mars was arrested early Sunday morning in Las Vegas on suspicion of cocaine possession.
Law enforcement officials told "Extra" that the singer, 23, was caught by Hard Rock Hotel security who confronted him in the restroom just before 2 AM. They then called Las Vegas Police who popped Mars aka Peter Hernandez, for possession of 2.6 grams of a "white powdery substance" believed to be cocaine.
Bruno was taken into custody, booked and released to his own recognizance around 7:45 AM.
The 23-year-old had performed at the Hard Rock on Saturday prior to his arrest.
