The Irish judge seriously lost his cool at the ITV talent show’s press event on Thursday (8 December) when we quizzed him about a potential Chezza comeback.
Louis - who has been vocal about his love of working with current co-stars Nicole Scherzinger, Sharon Osbourne and Simon Cowell - was less than impressed when we asked how he would react if Simon invited the former judge to return in 2017.
He spat: “Simon wouldn’t invite Cheryl back because we have Nicole. We have Nicole and Sharon - we don’t need another girl. So go and fuck off now. No silly questions, seriously.”
The music manager, who was on the red carpet with his finalists 5 After Midnight, then whacked the microphone that was being used to record the interview.
“It’s not about Cheryl. Don’t be stupid man.”
As he later asked us why we had posed the question, he continued: “It’s been a lot of fun behind the scenes but you wouldn’t know that - I know that.”
As we then explained Cheryl’s part in the history of the show, Louis then said: “Well she’s not for me... so fuck off. And you need a haircut.”
Louis and Cheryl have a long and complicated history and have traded many public blows since he was Girls Aloud’s manager, following their time on ‘Popstars: The Rivals’ in 2002.
The pair appeared to have called a truce during their last stint on the show together in 2014, but he reignited their feud when he made a series of catty comments about her and Rita Ora upon his return earlier this year.
‘The X Factor’ final airs on Saturday and Sunday at 8pm on ITV.
