Ariana Grande: Power of Youth Pretty

Ariana Grande keeps close to Justin Bieber backstage at Variety‘s 2010 Power of Youth event at Paramount Studios in Hollywood on Sunday (October 24).

The 17-year-old Victorious starlet performed at the event singing Christina Aguilera‘s “Beautiful” and a new song which was written by Billy Steinberg.”

Billy actually wrote Madonna‘s “Like A Virgin.” So cool!

Ariana also shared with us about costar Victoria Justice‘s honor, “I’m so excited. She’s so awesome and I think it’s great that she’s being honored today.”
