5 After Midnight might become a duo for their latest X Factor 2016 performance this Saturday.
It's after one of the band - Kieran Alleyne - was struck down with illness.
According to The Sun newspaper, Kieran has been sick all week with a stomach bug and has missed rehearsals to rest.
It could leave bandmates Nathan Lewis and Jordan Lee having to perform without him at the weekend.
“Feel so sick today!!” Kieran tweeted earlier in the week before sharing a picture of himself poorly in bed last night.
However it does seem as though Kieran might be getting better, posting about enjoying a party tonight.
"Launch Party 🙌🏽🙌🏽🙌🏽" he cryptically wrote online to fans.
Performing as a duo could be the latest setback the group has had, following a last minute song change last weekend.
The three piece have also had to dismiss claims that they could split up after backstage rows.
Jordan assured fans last week: "We're going to have arguments no matter what. If you have a child, you're going to have an argument with that child, but it's because you love them! It's the same with housemates and workmates."
Kieran added: "It's never anything serious. It's just petty, like brothers."
And he concluded: "We're not going to split up. We entered this competition together, we'll go out of it together."
Nathan joked: "We're not even at the end of this show yet, and it's like alright guys, it's been a good run - 20 weeks!"
The X Factor 2016 airs this Saturday and Sunday night at 8PM on ITV with the latest live show.
It's Disco week and there will be performances from Olly Murs and Nathan Sykes.
