Leona Lewis, Shayne Ward and Alexandra Burke aboard X Factor All Stars

Leona Lewis, Shayne Ward and Alexandra Burke are back to where it all began for The X Factor All Stars, according to former Judge Louis Walsh.

The three former winners would have signed up for the long-awaited edition of the ITV show, which should be broadcast this fall.

"It's going to be great, and then we'll do the best of all in a week, all the winners will come back," the 66-year-old judge told the Mirror.

"Leona comes back, Alexandra, Shayne, they all come back."

Shayne won the second X Factor series in 2005 before being screened on Coronation Street.

Leona won the third series of the series in 2006 and has had a successful career ever since.

Alexandra won season five in 2008 and performed an unforgettable duet with Beyoncé in the final.

Louis also explained how the new series would work, saying that after the shooting of the Celebrity version, Louis and the other judges will then film the All Stars version with the previous winners.

He added, "It was as long as the old X Factor had to change.

"I do not know what he's preparing for next year, but this year, I think the celebrity version will be brilliant and the best of it will be like, wow."

Exciting!

Judges who will join Louis for the X Stars edition and X Factor celebrities are Simon Cowell and Nicole Scherzinger.

Earlier this week it was announced that rugby stars Thom Evans, Ben Foden and Levi Davis are about to form a group of boys for the special.

Eyal Booker of Love Island, Samira Mighty, Wes Nelson and Zara McDermott would also be on the program.

It has also been previously reported that reality TV star Gemma Collins was in talks to appear in the show.

The X Factor celebrity edition will be broadcast this fall on ITV.
