Ariana Grande & Iggy Azalea Team Up for “Problem” at Wango Tango

arianagrande-wangotango-051214Some of the biggest names in music took the stage at the Stub Hub Center in Carson, CA on Saturday for KIIS FM’s annual Wango Tango.

Ariana Grande commanded the stage as she performed some of her hits including her latest single “Problem.” For the first time, Ariana was joined on stage by Iggy Azalea who also later performed her song “Fancy.” Big Sean also hopped on stage with Ariana.

We love Ariana’s retro mod black and white wardrobe which we can expect to see in her upcoming “Problem” music video.
