Katy Perry, the host of the night's awards, won for best new act.

Pink's "So What" was named "most addictive" track. And 30 Seconds to Mars won the "rock-out" awards for "A Beautiful Lie."

"This has been a really exciting week for us Americans," said frontman Jared Leto, who got the crowd to chant "Congrats Barack."
