The X Factor is set for an 'All Stars' special - who could be on the line up?
A potential X Factor All Stars series is said to be in the works for this year in place of the usual series.
Show boss Simon Cowell announced the plans in February, with a series featuring a line up of past contestants.
Simon said at the time “I’ve had a meeting with ITV, I’ve told them what I think we’d like to do with X Factor because we’ve been waiting to have this opportunity."
As yet no exact details have been confirmed but there have been rumours about who will - and who won't - be on the line up.
According to The Sun newspaper, Simon is keen to get a number of winners back including both Leona Lewis and Shayne Ward.
Also said to be in talks include the likes of Chico, Same Difference, Jedward and Honey G.
However a number of former X Factor contestants have ruled themselves out of the show.
Saara Aalto was runner up on The X Factor in 2016 but this week said she wouldn't be returning to any All Star season this year.
"I just did it two-and-a-half years ago so I feel it's a bit early," she said earlier this year. "I'm doing Dancing On Ice and I'm just exhausted. I've done so many reality shows now."
Current coach on The Voice UK, 2009 X Factor runner up Olly Murs also said no to a return. He told This Morning: “I wouldn’t go back on it, no.”
And while Rylan Clark-Neal said he "literally cannot wait to watch it", he said he wouldn't be returning.
Fleur East was a little more coy when discussing rumours of the All Stars, saying: "I’ve done X Factor twice now, it gave me a huge platform but I don’t know if I want to go back and change those memories.”
2017 winners Rak-Su also didn't say no while chatting on Lorraine, but suggested: "It's a bit early for us, I think. I think there's some people who had amazing moments and then things have gone a bit quiet, so I guess it would be great for them to reinvigorate things."
2013 X Factor winner Sam Bailey however is up for a return - on one condition.
“I’d love to go back with other winners and perform again . . . so long as they fed me egg and chips in the canteen!” she said previously.
Another contestant who is up for the show is 2014 X Factor contestant Stevi Ritchie.
The X Factor typically airs from September on ITV but scheduling for this year has not been announced.
