Simon Cowell has confirmed some details of this weekend’s X Factor final, including who the singers will be duetting with.

Speaking at a press conference Cowell said:

“We’ve got a lot planned. I’m not going to reveal everything, but what I can tell you today is who’s singing with who.

“Olly will be duetting with Robbie Williams, Joe will be duetting with George Michael and Stacey will be duetting with Michael Bublé.”

He added: “That is a big deal for these contestants and I think the duet will be a very significant part of the competition.

“Beyoncé last year was a huge part of why Alexandra [Burke] won, so I think these duets are becoming increasingly important now… and there’ll be a few surprises on Sunday.”
