At the X Factor Final press conference yesterday, it was officially confirmed that Robbie Williams, Rihanna, Will.I.Am and Christina Aguilera have all signed up to appear in the final, in a last ditch attempt to help each contestant win the X Factor crown.

Despite Dannii Minogue apparently being keen for her boy Matt Cardle to team up with Christina Aguilera - the lucky man has been paired up with diva Rihanna - who appeared on the show earlier on during the series.

Cheryl's mini-me, Cher Lloyd has been partnered up with her mentor's close pal Will.I.Am, who wowed the crowds when he performed with the Black Eyed Peas last weekend, and has previously confessed to being a fan of the rapping teen.

With Robbie Williams having rejoined Take That to great success this year, he's about to try his luck out with another boy band - as he's becoming the 6th member of One Direction for a night.

Which leaves Rebecca Ferguson to pitch her vocal talents up against Christina Aguilera, in a pairing reminiscent of the duet between Beyonce and Alexandra Burke back in 2008.
