Fun. opened the MTV Movie Awards in a big way. The New York band performed their massive hit ‘We Are Young,’ a song so ubiquitous that frontman Nate Ruess’ voice was at times drowned out by the singing crowd.

Donning matching white tuxedos, Fun. charmed everyone — even Vanilla Ice was spotted smiling and rocking out to the drunken anthem.

The crowd went especially wild when Janelle Monae, sporting a black suit and matching hat, came out to sing the bridge. It got a little messy on an audio level during this portion, as there was so much going on that it almost was sonic pandemonium. However, everyone regained their footing pretty promptly.

Toothy Ruess was clearly thrilled to be there, at times looking amazed that he was sharing the stage with Hollywood’s biggest names. Considering their song is one of the biggest of the year, they’ve more than earned it.
