Louis Walsh is taking revenge on Simon Cowell for booting him off The X Factor - by joining BBC show Any Dream Will Do, reports Mirror.
Louis will help out the series in which people audition for the lead role in Andrew Lloyd Webber's Joseph and the Amazing Technicolor Dreamcoat.
It will go head-to-head with ITV's rival Grease is the Word - which is produced by Cowell.
Louis is said to have jumped at the chance; a source revealed: "He was really hurt by the way Simon dropped him without even speaking to him directly.
"The BBC moved fast to ask if he'd like to help out.
"He is delighted to be working for the Beeb - and the fact that he'll be going up against Cowell's show makes it even sweeter."
