You know your Justin Bieber cover is good when the man himself endorses it. We were blown away by Ariana Grande's cover of "Die In Your Arms" -- and so was Justin. The "Victorious" star took the jazzy love anthem and added a light, ethereal touch that's just as good as -- or even better than -- the original. Watch and listen as she plays the piano, sips soda with her best friend Alexa and dances on a retro-fab set.
This weekend, the Biebs tweeted "WOW..u killed it @arianagrande
Ariana is the latest in a string of artists the Biebs has given his Twitter stamp of approval. Earlier this month, he called budding 13-year-old singer Madison Beer a "future star", causing her name to trend worldwide and her cover of Etta James' "At Last" to rack up more than 200,000 views on YouTube. And let's not forget Bieber's first big success: Carly Rae Jepsen.
Arianators who have been patiently waiting for more music from their favorite "Victorious" star won't have to sit tight for much longer. This spring, Ariana told Teen.com that her upcoming album is almost finished and that she's already chosen her first single.
