Katy Perry will be joined by Missy Elliott for her Super Bowl performance.

The 30-year-old pop star will reportedly duet with the rapper during her half-time show at the showpiece NFL game later today between the Seattle Seahawks and the New England Patriots.

The New York Daily News reports Perry will be joined by Elliott for at least one segment of the concert.

The 43-year-old hip-hop legend features on a remix of Perry's single Last Friday Night (T.G.I.F.) and rumours are rife that will be the track she's guesting on.

Perry has already confirmed that rock guitarist Lenny Kravitz will join her on stage and she hinted at Elliott's appearance, saying the gig will be a "female fun night".

Speaking at a press conference for the Pepsi Super Bowl XLIX half-time show at the Phoenix Convention Center, she said: "It's going to be wild out there. I'm creating three or four different worlds ... I have to keep some surprises but I'm very, very excited about this guest.

"I thought long and hard about it. People are not going to expect it.

"It's a throwback of sorts that definitely needed some shine. All I can say is that it will be female fun night but when this person enters the stage faces will melt.

"There will be some faces melted when she steps on the stage."
