Watch Ariana Grande and Iggy Azalea Go Mod for Problem Video
Ariana Grande's summer hit "Problem" is currently sitting at No. 2 on the Hot 100  just below her featured guest Iggy Azalea's team-up with Charli XCX, "Fancy"  so now that the video's out, don't be surprised if Grande overtakes her collaborator in the No. 1 spot. But the girls play nice in the mod-styled clip, which sees Grande reprising the choreography she's showcased in previous performances while Azalea rocks the biggest hair of her career. Play it again, Mr. Saxobeat.
