Listen to Usher Radio on iHeartRadio

Usher Radio

Usher gave an amazing performance at our iHeartRadio Music Festival. He performed all of our Usher favorites - but he really turned up the heat (literally) when he invited Chris Brown on stage!

The guys performed "New Flame" from Chris' most recent album x, which flowed right into a dance off. They went HARD. Usher danced right out of his shoes ... and then set them on fire! Seriously.


Good thing he had back-up!
