Gaga will be in the country to promote her new album 'The Fame Monster' and will sing new single 'Bad Romance' on The X Factor.

Jackson and Gaga join a host of acts who have performed on the results show in 2009 including Robbie Williams, Leona Lewis, Bon Jovi, Whitney Houston, Westlife and Queen.

As reported earlier today, Sir Paul McCartney has revealed he's in talks to appear on The X Factor final.
