Bruno Mars is apparently being lined up to sing with Fleur East on The X Factor 2014 final.
The duo are reportedly set to sing Uptown Funk together, even if Fleur only just performed it for the first time on Saturday night.
Fleur's cover of the unreleased track has shot straight to Number One on iTunes after the weekend's latest live show.
The Daily Star newspaper now says that bosses are "lining up" Bruno to duet with Fleur this Saturday night.
However a duet with Megan Trainer could also be on the cards with Fleur having performed her hit All About That Bass at the start of the live shows, another performance that went down well.
Unlike Bruno, Megan has already been confirmed for this weekend's X Factor 2014 final.
Sam Smith and Ed Sheeran have also been announced, with speculation that they too could be set to duet with the other finalists Andrea Faustini and Ben Haenow.
A range of EVEN MORE guest stars have been revealed as well, including former X Factor finalists One Direction and Olly Murs, and Demi Lovato.
While the stars have been confirmed, it's not expected that we'll hear any official word on the duets before Saturday's final itself.
