Clad in her mod black-and-white attire, the pint-sized diva performed a 15-minute set of her biggest hits including “The Way” and “Right There” with Big Sean.

For the first time, Iggy Azalea joined her onstage to deliver their collaboration “Problem,” which debuted at No. 3 this week. The Aussie rapper also treated the packed arena to her own hit single “Fancy.”

Saturday’s star-studded lineup also included Kid Ink, B.o.B, Shakira, Maroon 5, and Ed Sheeran.
