Ariana Grande, Iggy Azalea & Cody Simpson Perform At ‘Dancing With The Stars’ Finale: Watch

Ariana Grande performed her smash hit “Problem” during the May 20 Dancing With the Stars finale. Judging by how NeNe Leakes was dancing, this time will hardly be Grande’s last.

But before Grande took the stage, Iggy Azalea and Charli XCX performed “Fancy.” Both stars were in plaid, though they weren’t dressed for Clueless. Instead, with cat-eye glasses and a sash as accessories, both appeared as they would for a sock hop-themed prom. (Azalea would later apologize to fans for technical issues, though she quickly recovered.) Then Cody Simpson performed his new single “Surfboard,” posing as a surf rock frontman but also chirping like a Boost Mobile and actually singing, “She on my surfboard, gonna ride it – surfboard!”

So by the time the Yours Truly star appeared, posing on a motorcycle and dressed in sleek black separates, it was clear that all the finale performers were assigned a theme, just like the show’s contestants.
