Cheryl Cole has been a massive hit since joining the X Factor judging panel and there is speculation Simon Cowell may spice up next year's show with another fresh face.
Dannii Minogue has been made to look a little old hat by the younger model on her left and Cowell continues to have a fiery relationship with Louis Walsh, so either one could get the boot.
Paula Abdul is a 12/1 chance with Paddy Power to switch across the Atlantic after being replaced on American Idol by Ellen DeGeneres and Sharon Osbourne is the same price to be recalled.
However, there are some far more interesting names also featured on the Irish firm's list of potential candidates to cast a glaring eye over future contestants.
Eminem is 8/1 favourite in the market over who will be next to join the X Factor judging panel and as well as being a major coup for Cowell he does share a similar hairstyle and stature with Louis.
Robbie Williams is one name you would expect to appear on this list and he is next best at 10/1 to step in, with former Take That buddy Gary Barlow 14/1.
Will Young at 12/1 would be another ideal candidate given his victory in the inaugural Pop Idol back in 2002 and subsequent chart success, while Ronan Keating also catches the eye at 20/1.
As for a new female recruit, Lily Allen leads the way on 10/1 with Paddy Power, followed by the safer options of Abdul and Osbourne.
Victoria Beckham and Mel B can both be backed at 14/1, with fellow former Spice Girls stars Emma Bunton and Geri Halliwell 18/1 and 20/1 respectively.
Charlotte Church is a 16/1 chance to add some classical knowledge to proceedings, with Myleene Klass 20/1 alongside Madonna.
