Here's a latest look at who The X Factor 2015 judging line up could be come the summer.
Nothing has yet been confirmed officially although Louis Walsh has all but announced his exit.
Together with Mel B's rumoured axe it leaves two seats free alongside Simon Cowell and the near-certain return of Cheryl.
One Direction's Louis Tomlinson has been backed into 6/4 from 2/1 with Boylesports, as punters seem to believe he would be the perfect replacement but Robbie Williams has also shortened for the role and can now be backed at 7/2 form 5/1.
While Robbie has insisted he's 'too busy' for job, he's still being backed by Louis Walsh as well as new hosts Olly Murs and Caroline Flack to join the show.
Rita Ora remains a strong contender for the job, despite reports she is looking to judge on the a return for the US X Factor, at 11/10.
Nick Grimshaw is a newcomer to the betting, but has gone straight in as one to watch at 3/1 and another One Directioner’s name in the mix is Niall Horan, who was recently gambled on to leave the group and is 7/1 to take a seat on the 2015 judging panel.
Tulisa is fancied at 8/1 to make a comeback while former X Factor champ Leona Lewis is at 18/1.
Aoife Heffron at BoyleSports said: “Nick Grimshaw would spice up the X Factor with his wacky ways and he has received strong support from punters since going into the betting at 3/1 just a couple of days ago.”
She added: “Louis Tomlinson has been backed off the boards since Louis Walsh confirmed that he would not be returning as a judge, however following the recent bets on Niall Horan to leave One Direction Niall is seeing some shrewd bets at 7/1.”
The X Factor will air in the autumn on ITV with an official announcement about this year's panel expected soon.
