UK X Factor judge Cheryl Cole has reportedly agreed to appear on the German version of the talent show.

As part of her European promotional tour, Cheryl will mentor the singing hopefuls and possibly also perform on the show.

A source close to Mrs Cole told The Mirror: “She’s thrilled to start her European campaign in such a big way. The X Factor’s huge in Germany. There are also plans for her to be a guest on the biggest shows there too – including Wetten Dass – they’ve had Madonna and all the A-List stars in the past.”

On whether she will return to X Factor UK for the 2010 series, the source added:

“Who knows what will happen. She loves the show but her solo career comes first and if schedules collide then she may not return. She wants to spend time in America too – and may commute between X Factor auditions to make it work out there.”
