On Tuesday, host Kevin Hart announced that Nicki Minaj will perform as a surprise guest with a previously announced performer.

At the press event on Tuesday, Hart also announced that rapper 2 Chainz will be performing and Demi Lovato, Rita Orr and Psy would all appear on the show.

Previously announced performer Rihanna will open the show, which airs on MTV on Thursday, Sept. 6. She’ll perform “Cockiness” featuring A$AP Rocky and her hit song “We Found Love.”

Three of the five U.S. Olympics gymnasts were also present at the press event. Gabby Douglas, Kyla Ross and McKayla Maroney announced that Lil Wayne will be performing his new song “No Worries” and that Katy Perry would give out the first award for best pop video.

Hart, who will host the VMAs for the first time on Thursday, told reporters that he planned on taking some jabs at members of the music community during his opening monologue.

“The beauty of me being the host is you don’t know what to expect. Nobody is off limits,” he said. “I think it’s my job to put the room in a place where people can relax and have a good time and the best way to do that is to show people they can poke fun at themselves.”

The MTV Video Music Awards will air live on Thursday, Sept. 6, from L.A.’s Staples Center.
