Viewers saw the boys – Jordan Lee, Kieran Alleyne and Nathan Lewis – disagreeing over dance moves in a VT aired on Saturday night ahead of their Divas and Legends Week performance.
Choreographer Brian Friedman told the camera the boys weren't agreeing or talking, which was eating up his time.
Later, when the group chatted to their groups' mentor Louis Walsh, they admitted to having a few arguments, comparing it to bickering with siblings.
Nathan confessed: "Having to work with each other and be at home with each other as well means there's a lot of pressure."
Kieran said: "You're like, give me my space, please people! But these are my brothers. You will have fights, but at the end of the day, it's all love."
Despite that, some viewers started worrying about the band's future, leading to headlines about a possible split on the horizon.
Er, NO say the boys!
Reacting to one story via Twitter, the group said: "Haha not at all!!! We are brothers and are staying in this together!!!
"Let's squash this rumour!! We really are not splitting up... if anything we are more solid than ever!! Bring on FrightNight!!"
Despite getting mixed reviews from the judges for their performance of 'Valerie' on Saturday night, the group are safely through to next week's Halloween show, which has a Fright Night theme. That theme was chosen by the jukebox on Sunday night, which raised eyebrows given the jukebox appears to be random…
X Factor continues 8pm on Saturday on ITV.
