Fans didn't get the dance battle they wanted, but Chris Brown and Usher put on a show at this year's iHeartRadio Music Festival in Las Vegas.

The singers took the stage to perform the hit single "New Flame." The two mimicked their dance routines from the video while Usher lit his shoes on fire at the end of the performance.

Other acts at the two-day festival included Nicki Minaj, Ariana Grande, 50 Cent, Iggy Azalea and Ed Sheeran.
