MTV News can exclusively confirm that the "X Factor" judge will be on hand for the festivities on September 21 when it all goes down at the MGM Grand. She will join fellow presenters "X Factor" co-judge Britney Spears and Olympian Ryan Lochte as well as Ryan Seacrest, who is set to host the event.
Among others, Taylor Swift, Rihanna, Usher, Lil Wayne and Pink have all been announced as performers at the two-day festival.
"The iHeartRadio Music Festival is a unique celebration of music -- it's the biggest names in the industry coming together for an impressive weekend of live entertainment," Seacrest said in a statement earlier this summer about the shows. "The momentum, energy and music experience around the inaugural iHeartRadio Music Festival was incredible, and I'm excited to be a part of this must-see event."
The new gig comes during a busy time for Lovato. She took the stage and a Moonman at the VMAs last week, and she's currently one of the newbie judges on the "X Factor," which kicked off earlier this week. And, she recently opened up to MTV News about joining the show for the revamped second season.
"I think people are really gonna like it. It's really funny," she shared. "It's really honest and there's tons of drama that goes on backstage between the contestants. Which I think is going to be pretty fun to watch."
