Katy Perry, who pointed out that she was never nominated but still has her own eyelash line, presented the 2013 Grammy for Best New Artist to Fun., making it their second golden Gramophone of the night.

The 'We Are Young' band knew they were up against steep competition and acknowledged it accordingly. "I didn't think we were gonna win this one to be honest, Frank Ocean, the Lumineers -- I gotta pee so bad, so I'm gonna leave it up to these two guys," Nate Ruess said to uproarious laughter.

Jack Antonoff and Andrew Dost thanked their touring crew, friends, family and staff as Antonoff's girlfriend, 'Girls' star and creator Lena Denham, clapped her heart out in the audience.

Ruess closed out their speeches with the antithesis of their breakthrough Song of the Year-winning hit: "We're so old!"
