The 2013 VMAs rocked Brooklyn, New York last night. And we caught some of our fave Nick celebs making an appearance! The night kicked off with a quick pre-show concert featuring Austin Mahone and our very own Ariana Grande. And we couldn't be happier to see Ariana in action, doing what she does best... performing! She got the crowd pumped with her hit songs, "Baby I" and "The Way," and proved she knows how to own the spotlight.
