Former Pop Idol winner, Will Young will guest star on this years X Factor series despite a long running feud with judge, Simon Cowell.

Will first developed a dislike for Simon when he performed on Pop Idol in 2002 only to have the music moghul brand him as “distinctly average.”

Will has also made it clear that he is no big fan of Louis Walsh either, saying:

“I just don’t think he’s a very clever person.”

A music industry source told The Sun: “Will doesn’t like Simon and Louis. However, it was this kind of show that gave him his career, he’s not about to turn his back on it.”

Will previously told us he will kiss and make up with Cowell, saying: “Simon and I exchanged a few cross words at the time but I have nothing but respect for what he has done bringing the show on.”
