Usher, Nicki Minaj, Ariana Grande To Perform At iHeart Radio Festival 2014

The iHeartRadio Music Festival will be making its way to Sin City once again this fall with big-name acts in tow.

In its fourth year, the weekend-long concert has tapped Nicki Minaj, Usher, Ed Sheeran, Iggy Azalea, Lorde, Calvin Harris, and more to hit the stage at the MGM Grand Garden Arena in Las Vegas on Sept. 19 and 20. Ryan Seacrest will also serve as master of ceremonies.

“Year after year the iHeartRadio Music Festival continues to deliver an unprecedented music experience for millions of fans nationwide,” Seacrest said. “I couldn’t be more excited to be part of it.”

For those unable to make their way to Vegas, the iHeartRadio Music Festival will broadcast live on Clear Channel radio stations for fans throughout the country across 150 markets and will stream live on Yahoo Screen each night at 7:30pm PST. The iHeartRadio Music Festival will also return to The CW Network as an exclusive two-night special on September 29 and 30 from 8-10pm.
