In an exclusive live video, only available on Radio.com, Murs performs his latest single "Troublemaker" for a sold-out crowd at his January show at the House Of Blues in Los Angeles. "I know for a fact there's plenty of U.S. troublemakers in here tonight," he said with a smile.

Just saying those words made the ladies in the audience go wild, and we mean ladies since you'll be hard pressed to spot anyone with a Y-chromosome in the crowd. Seriously, just try!
