2015 Billboard Music Awards: Watch All the Performances

The 2015 Billboard Music Awards packed its three-hour broadcast chock full of incredible musical performances and collaborations on Sunday night (May 17). Most notably, Mariah Carey returned to the live TV for a medley of her 1990 No. 1 single "Vision of Love," then transitioned to her latest single "Infinity," despite vocal illness. Britney Spears and Iggy Azalea debuted an energetic (if not live-sung) performance of their new single "Pretty Girls."

Other performances include Fall Out Boy's "Uma" with Wiz Khalifa, Nick Jonas' retro-futurized "Jealous," Kelly Clarkson, Pitbull, Tori Kelly, Nicki Minaj, and so many more. You can watch all of the performances below.
