Bruno Mars waive his preliminary hearing on felony drug possession charges at the Clark County Regional Justice Center, Feb. 4, 2011, in Las Vegas. After a September 2010 concert at the Hard Rock's Wasted Space nightclub, a bathroom attendant noticed Mars was taking a long time in a stall accompanied by a little bag of white powder. A security guard confronted him as he left, and Mars ended up getting probation and community service for a cocaine charge. All this happened as his song "Just the Way You Are" climbed the Billboard charts.
