Ariana Grande and Iggy Azalea Perform “Problem” at 2014 Billboard Music Awards (VIDEO)

Ariana Grande is unstoppable. The 20-year-old singer has been on a whirlwind media tour promoting her chart-topping single “Problem.” Her latest stop? The 2014 Billboard Music Awards, where Ari was joined on stage by Aussie rapper Iggy Azalea.

The diva-in-training performed in a black-and-white dress, flaunting her pipes and mimicking a few of Bob Fosse’s most memorable moves. Iggy then joined her on stage for her rapid-fire guest verse. Cue adorable synchronized choreography!

Ariana and Iggy are both successful newcomers to the industry, and they definitely left a lasting impression on the music legends in the house at the MGM Grand Garden Arena on May 18 in Las Vegas. “Problem,” featuring Iggy, debuted at No. 3 on the Billboard Hot 100 after selling 438,000 downloads in its first week — the fourth-biggest start for a song by a female artist. Way to go, Ariana!

Meanwhile, Iggy’s hit single “Fancy,” featuring Charli XCX, currently stands at No. 3 on the Hot 100. With "Problem” now at No. 4, Billboard reports that Iggy is the first female rapper ever to have two songs concurrently in the Top 5 of the Hot 100 chart. Clearly, Ariana and Iggy aren’t showing signs of stopping anytime soon — and we couldn’t be happier!

Watch the performance below and tell us what you think in the comments. Look for Ariana to drop her highly anticipated sophomore album sometime this fall.
