Mike Posner Performs 'Cooler' On America's Got Talent

Overnight sensation Mike Posner proved just how cool he was when he performed his lead single, "Cooler Than Me," on the "America's Got Talent" results show last night (Jul. 28). Posner had the place jumping, literally, as he paraded around the stage in a military stamped leather jacket.

"Just be yourself and good things will happen," Posner advised the audience after his performance. "Cooler" has spent 13 weeks on the Billboard Hot 100 chart, making the small slip from 6-7 this week.

The Duke University graduate's debut album "31 Minutes to Takeoff" comes out Aug. 10 followed by a nationwide tour.
