Leona Lewis and George Michael are the two latest star names linked to appearing on the new series of The X Factor.
Former winner Leona is tipped to fill in for the departed Kelly Rowland during the audition stages of the show, with that position currently being filled on a temporary basis by Geri Haliwell.
However, Geri has her eyes on making her current guest role permanent and has claimed that she would recruit her friend George Michael for the Judges Houses stage if she were kept on for the whole series. Clearly, this would be a big draw for viewers and could secure her the position.
"Whoever I bring in as my guest helper will be authentic to me. It wouldn't be [a] 'rent-a-celeb'," Geri told The Sun.
Adding: "I'd possibly ask George, as that feels authentic. It would either be him or my mum."
Other stars linked to the fourth judging spot include Robbie Williams, Katy Perry, Mel B, Rita Ora and Dannii Minogue.
