Take That front man Gary Barlow could be forced to pull out of appearing on this years series of the X Factor due to his commitments on the Queens Diamond Jubilee celebrations.

Gary is already locked in the studio with legendary musical master Andrew Lloyd Webber penning a new song for Her Majesty while he is also scheduled to tour the Commonwealth for a special documentary as well as being given the almighty task of planning the extravagant Jubilee concert set for June 4th.

Simon Cowell is said to be working hard on re-arranging the X Factor audition schedule so that Gary can still play a part but fears are growing that the lyric master may just be too busy. A source said, “Gary wants to go back and Simon wants him but he has got a lot on this summer, namely the Jubilee concert which is taking up a lot of his time and other projects he is working on mean that unless the audition schedule changes, Gary won’t be an X Factor judge for this year’s show, which will be a huge blow for Simon.” They continued, ”He loved the X Factor line-up last year and he hopes that he will be able to keep it the same. It is going to take a lot of juggling around though.”
