Leona Lewis looks set to go head-to-head against Ray Quinn on 'X Factor All Stars'.
The 34-year-old singer and Ray, 30, could both star on the much-discussed show, which will see a host of famous faces return to 'The X Factor' stage.
A source told The Sun Online: "Show bosses are in talks with Ray and are hopeful he will sign on the dotted line - he's really keen to be involved especially with Leona Lewis in the mix and it will be amazing to bring their big voices back to the 'X Factor' stage."
'X Factor All Stars' is one of two shows reportedly poised to replace 'The X Factor' in 2019, with Leona - who competed against Ray on 'The X Factor' back in 2006 - set to return to TV screens across the UK.
The speculation comes shortly after it was reported that Leona is set to get married this weekend.
The singer has been in a relationship with choreographer Dennis Jauch for nine years, and she's set to embark on the next chapter of her life, as she and Dennis are planning to marry in Italy.
A source said: "Leona is madly in love with Dennis and they are both so excited to get hitched this weekend.
"They have flown their nearest and dearest out to Italy for the ceremony and no expense has been spared.
"She has spent months and months making sure everything is perfect for the big day and they have loads of pals coming from the UK as well as the US. Because they live in the States, their friends and family don't all get to meet up much, so it's going to be a really special day."
