Ariana Grande Rocks iHeartRadio Pool Party

Ariana took the stage at the iHeartRadio Pool Party (airing Wednesday, July 9, CW) and the superstar definitely proved, once again, that she is all grown up with her sexy getup. Goodbye, Nickelodeon!

Ariana wore her hair in a high ponytail and a sexy, summery purple crop top with a matching sheer skirt — and, of course, her signature knee-high white boots.

Fans always go crazy for Ariana, but the crowd went wild when they realize that two stars are on the stage — there is no voiceover from Iggy Azalea. It’s actually her!
