Rihanna, Lil Wayne, and Usher Heat Up iHeartRadio Music Festival

Music’s biggest stars aligned in the desert for the second annual iHeartRadio Music Festival in Las Vegas on Friday. The first day of the two-day music extravaganza kicked off with performances from Lil Wayne, Usher, No Doubt, Green Day, Rihanna, and more.

Weezy was the sole hip-hop act on the bill, delivering his greatest hits and bringing out Keyshia Cole for “Enough of No Love.” Usher paid homage to Michael Jackson with his choreography during his 25-minute set, serving up his sizzling singles “Climax” and “Burn.”

Shimmering in a Jeremy Scott jersey dress, New Era cap, and Jordans, Rihanna closed out the first day of the festival with an Egyptian-themed set and plenty of hits including “Only Girl (In the World),” “Disturbia,” and “We Found Love.”

The festival continues today with Mary J. Blige, Pitbull, Taylor Swift, Pink, Aerosmith, and more.
