Ariana Grande closed out the 2014 MuchMusic Video Awards Sunday night with a rousing performance of 'Problem' that brought the house down in Toronto, Canada. Her show was so big that she and her dancers performed on all three stages at the live awards event.

Grande made her Canadian television debut in front of a crowd of screaming fans and appeared on stage wearing a glittery dress. The stage backdrop features many of the patterns seen in the 'Problem' music video, such as the retro black and white swirls.

It's no surprise that 'Problem' is quickly becoming the hit of the summer. It was released on iTunes at midnight, April 28, and the single became the fastest selling song to reach No. 1 on iTunes’ singles chart.

She's currently still hard at work on her second studio album, which still has not yet been named but is expected to be released later this year.
