Barlow and Allen could join the X Factor

Gary and Lily are being considered as judges

The musicians are hotly tipped as the two celebrities to join the popular show.

The new season of the X Factor will have five judges instead of four as Simon Cowell will only appear on the live shows, on Saturdays and Sundays as he'll be busy with the American version in the States.

It is understood that Cheryl Cole will not join Louis Walsh and Dannii Minogue on the panel as she's still in the running for the judge job in the USA.

Speaking to the Mail on Sunday, ITV boss Peter Fincham said "We will announce plans for the panel when we are ready. But what I can tell you at this stage is that the new series of The X Factor will be very new and very different from what we have seen before".

Auditions for the show will kick off in May.
