Without Rihanna giggling at her this time around (find out what Ariana said about that, by the way), we could focus completely on Ariana and her amazing pipes. Having adorable backup dancers doesn't hurt a performance either, but all we really need is Ari's voice.
And that outfit? Can you say skintight sexy? Ariana busted out some cutesy dance moves of her own while singing and we don't even know how she managed to flawlessly hit those high notes without completely losing her breath.
Amazing.
