Singer/songwriter Bruno Mars — the man behind pretty much every radio hit this past summer — was arrested early Sunday morning in Las Vegas on drug-possession charges. On Monday the Las Vegas Police Department released a copy of the arrest document, which revealed Mars was taken in for felony possession of 2.6 grams of a “white powdery substance†that tested positive as cocaine. The 23-year-old, who had performed a concert earlier Saturday evening, has been ordered to return to court on November 18 for his arraignment. [MTV News]
