Rhydian to duet with Katherine Jenkins?

Katherine Jenkins is being lined up to perform a duet with Rhydian Roberts on this week's X Factor final, it has been revealed.

Rhydian's mentor Dannii Minogue is in talks with the opera star to appear on the show because she thinks the pair, who are both Welsh, will be "amazing" together.

A show insider told the Daily Star: "It will be something truly special. Simon Cowell is going to have to do something big to win."

Minogue's other act Leon is thought to be singing with her older sister Kylie, but Cowell has not confirmed who will perform with his remaining act Same Difference.
