It was a night to remember as the KCA nominees took stage at the 2011 Grammy awards.

Justin Bieber spread the fever with two on-stage collaborations with fellow KCA noms, Jaden Smith and Usher! A candy-clad Katy Perry sang her dangerously delicious hits "Teenage Dream" and "Not Like the Movies". Selena Gomez made magic when she presented for "Best Pop Vocal Album", and Lady Antebellum got major country-kudos after snagging five awards!
