Christina Aguilera, Robbie Williams, will.i.am and Rihanna are set to sing duets with ‘The X Factor’ finalists on Saturday night (11.12.10).

The international stars have each reportedly agreed to be paired up with hopefuls Cher Lloyd, Rebecca Ferguson, Matt Cardle, and boyband One Direction in a bid to help them win the hit ITV1 show.

While it has not been confirmed who will be singing with who, insiders claim ‘Rock DJ’ hitmaker Robbie – who appeared on last year’s final to duet with second place contestant Olly Murs – will be paired up with Essex painter and decorator Matt.

However, it has also been suggested Matt’s mentor Dannii Minogue is desperate for him to perform his last song with Christina Aguilera, who is appearing on the TV talent show to promote a new song from her film ‘Burlesque’.

An X Factor insider said: “A duet between Christina and Matt would be a magical moment – just like when Beyonce dueted with Alexandra Burke during 2008’s final.

“Matt’s voice is phenomenal and Christina can hit notes no one has dreamed of. They would be a perfect pairing no matter what song they sang.”
