Susan Boyle will perform on the X Factor this November as part of a campaign to promote her new album. Also reportedly making an appearance over the series, will be former winner Alexandra Burke, runners up JLS and show judge Cheryl Cole.

A show insider told The Mirror: “It makes perfect sense and will create a big buzz.

“There are two shows to fill on Saturday and Sunday nights now, so they’re also planning guest appearances from previous winners and runners-up as well as celebrity guests.”
