Susan Boyle will be appearing on The X Factor next Sunday night. She will sing her debut single ‘Wild Horses’ from her upcoming new album.

Also on the show will be THE diva herself, Mariah Carey

“We’re going all out to annihilate Strictly this year,” a source told The News Of The World. “These big signings will really help us.

“Simon is very excited about Susan coming back but wants to make sure she excels. It’s going to be nerve-racking for her being at the very same place where she lost Britain’s Got Talent. The pressure can get to her and he’s decided not to sign another big-name act for that night so everything is focused around her.”
