He might be locked out of heaven but Bruno Mars has done pretty well for himself in 2013. The 28-year-old singer has been named Artist of the Year by Billboard music magazine and is estimated to hold a net worth of $15 million USD. Pictured on the magazine's cover in a white 'wife beater' vest with a quaff and tattoo bearing his mother's name the California-based musician looks more like Elvis than the Prince-inspired R&B funkster he's gained his fame as. "It's flattering. It's an honor," the Hawaiian performer said of his new title. "I'm proud to be a part of this whole team," he added. The Unorthodox Jukebox star is currently nominated for five Grammy awards. Meanwhile his singles "Locked Out of Heaven" and "When I Was Your Man" have consistently topped the charts.
