Ariana Grande Performs "Problem" at MuchMusic Awards, Raps Iggy Azalea's Part

by at . Comments

Ariana Grande delivered another strong performance of "Problem" at the MuchMusic Video Awards last night, even rapping parts of Iggy Azalea's verse.

Donning her signature knee-high boots and classic up-do, Ariana's sexy-yet-understated dance moves were almost as impressive as her voice.

That's always been her calling card, though. Safe to say she doesn't lip sync up there, because she doesn't have to. Girl has got talent and then some.

With a silver bra top and high-wasted skirt, Ariana looked like a sexy little disco ball up there. One that can actually carry a tune, to say the least.

For whatever reason, Iggy Azalea did not attend the 2014 MuchMusic Video Awards to rap with her, but the 20-year-old Grande picked up the slack.

Meanwhile, Miley Cyrus threw a tantrum after losing to Selena Gomez, and event co-host Kendall Jenner wore no underwear on the red carpet.

So yeah, there was quite a lot going on up in Toronto! Fortunately for Ariana Grande, she managed to remain scandal free. BUT FOR HOW LONG?!
