Chris Martin to Join Sir Paul McCartney and George Michael on X Factor?

A triumvirate of some of the biggest music stars on the planet is reportedly set to make live appearances on this weekend's 'X Factor' live final.

According to a report in the Daily Mirror, Sir Paul McCartney and George Michael will sing live duets with the remaining contestants -- Olly Murs, Stacey Solomon and bookies' favourite Joe McElderry -- on this Saturday's (Dec. 12) show.

It has now emerged that the show's Mr Big - Simon Cowell - is desperate to convince Coldplay front man Chris Martin to join the two musical legends on the show. Cowell has apparently told friends that he is keen to pull a record-breaking audience of over 20 million viewers by laying on spectacular final.

A source was quoted by the paper as saying: "Everyone knows Simon is ultra-competitive and he has always said he will only carry on with the X Factor if he can improve on it year-on-year.

"After last year's duets with Beyonce, Boyzone and Westlife he knew he had to pull out all the stops to make this year's even better."
Sunday night's (Dec. 6) results show saw guest appearances from Janet Jackson - whose costume functioned to perfection - and Lady GaGa who performed her new single, 'Bad Romance' in a giant bathtub.
