Rihanna, Lil Wayne, Usher, and more of music’s biggest stars will meet up in Las Vegas for Clear Channel’s second annual iHeartRadio Music Festival this fall.

The two-day concert extravaganza will return to the MGM Grand on September 21 and 22. Hosted by Ryan Seacrest, this year’s diverse line-up also includes Mary J.

“I think the iHeartRadio Music Festival sets a very good tone for your credibility as an artist on radio right now,” said Rihanna. “I think it’s special that all the fans get to come together from all over to just have one huge concert. It’s a dream concert, 20 of their favorite artists that they’re hearing on the radio every day. They get to see them all at once and that’s special.”

Launched in September 2011, the inaugural iHeartRadio Music Festival featured performances from Lady Gaga, Jay-Z, Nicki Minaj, Alicia Keys, Jennifer Lopez, and more.

Tickets go on sale via Ticketmaster beginning Saturday, July 14, at 1 p.m. EST. Those at home will be able to watch the show broadcast live on iHeartRadio, Yahoo!, and Xbox.
