"She knows I’m writing a book, so it’s all fun and games, there’s no nastiness.”
However, Cheryl has now denied Louis’ claims, saying that her messages were not meant in a humorous way.
She posted on Instagram: “Back pedal until out of sight.
“Ps) I would not have found the text messages I sent to be ‘funny’ but ok!!
“Toodles,” she added, in an apparent dig at Louis being axed from the upcoming series of ‘The X Factor’.
The pair have an up-and-down history, as they first fell out when Louis managed Girls Aloud after they won ‘Popstars: The Rivals’ in 2002.
But they looked to have put their differences aside when they reunited on ‘The X Factor’ last year.
Following their latest spat, Simon Cowell compared them to cartoon cat and mouse characters Tom and Jerry, telling ‘Good Morning Britain’: "There was always going to be a clash."

As you probably know, Cheryl ended up becoming one fifth of Girls Aloud, the winning girl band of ‘Popstars: The Rivals’. The group were managed by Louis Walsh, but ended up sacking him fairly early on, when they realised they didn’t feel like was up to the job, and ended up managing themselves for a brief spell.

Of course, it’s not in Louis’ nature - or Cheryl’s, for that matter - to sit back and say nothing, later accusing her of not being able to sing, adding: “I'm a much better manager than she is a singer. If she comes back on The X Factor, she needs to sing live this time. I've got two words to say: vocal lessons.” (credit:Danny Martindale via Getty Images)

That didn’t seem to last, though, and in 2014 - once Cheryl had been re-appointed as an ‘X Factor’ judge, alongside Simon Cowell - Louis admitted that if Chezza was calling the shots, he probably wouldn’t be back. (credit:Niki Nikolova via Getty Images)

In the end, though, he did come back, although Cheryl didn’t seem too pleased to see him. During an interview with Graham Norton about her ‘X Factor’ return, she admitted Louis had given her a “frosty” reception, and when asked whether things were ‘off’ between them, she insisted: “They were never on!” (credit:BBC)
On Cheryl’s birthday last year, she uploaded a photo onto her Instagram page that showed herself celebrating on a private plane, along with Mel B, Simon Cowell and her husband. Louis’ absence did not go unnoticed. Ouch. (credit:Instagram)

And here we are… the saga continues, with Louis still claiming Cheryl is “irrelevant”, and Cheryl still suggesting Louis is “obsessed” with her. How very Mariah Carey of her...
