Louis Walsh has confirmed that Leona Lewis, Alexandra Burke and Shayne Ward are returning for X Factor All Stars.

The judge is about to begin filming on the celebrity version of the ITV show and says that the three previous X Factor winners will all be returning for All Stars.

Speaking to Mirror.co.uk, he said: "I go to Los Angeles on Tuesday, I go to Simon’s house in Malibu, it’s me Simon [Cowell] and Nicole [Scherzinger] and we’re doing the celebrity one.

"We haven’t been told who the celebrities are I’ve just read bits in the papers. They want it to be a surprise to us when they walk out.

"It’s going to be great, and then we do the 'best of' all in one week, all the winners are coming back. Leona's coming back, Alexandra, Shayne, they’re all coming back."

Once they've finished filming the celebrity version of the show, Louis and the other judges will then start working on All Stars.

"I don’t know what he’s [Simon] planning for next year but this year I think the celebrity version is going to be brilliant and then the 'best of' is like, wow.

He added: "Simon doesn’t want us to know who is doing the celebrity version and he doesn’t want to know. I’m going on Tuesday and we start on Wednesday.

"It’s going to be new and fun, it’s going to be Love Island meets everything, it’s going to be bigger and better."

The X Factor airs on ITV.
