Fun. Performs At MTV Awards show

Fun. opened the MTV Movie Awards this past week. The newly-arrived-on-the-scene band performed the giant hit ‘We Are Young.’

Fun. charmed everyone — even Vanilla Ice was spotted smiling and rocking out to the drunken anthem.

The crowd went especially wild when Janelle Monae came out to sing the bridge.The audio level got a little cluttered because of all the crowd noise, but they regained their composure and continued.

Toothy Ruess was clearly thrilled to be there, a signal that perhaps they had really hit the 'big time'.
