"It's all attention-seeking, so you have to let it go over your head. He'd turn on anyone at any time if it meant it got him into the press," she said.

Louis and Cheryl have been at loggerheads
The singer added that she reckons Louis will now fade into obscurity, as he's been replaced by Nick Grimshaw on ‘The X Factor’.
"He was just Simon's yes man. He did as he was told if it kept him his seat on the panel,” she said.
"He doesn't have any successful bands any more - ‘X Factor’ was the only thing that was keeping him out there, so hopefully there won't be any interest in what he's got to say now."
However, she denied that they were meant jokingly, posting on Instagram: “Back pedal until out of sight. Ps) I would not have found the text messages I sent to be ‘funny’ but ok!!”
Take a look at the history of their feud below...
Cheryl Fernandez-Versini And Louis Walsh's Feud
2002 - Girls Aloud(01 of10)

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.

Cheryl first joined ‘The X Factor’ in 2008, replacing departing judge - and Louis’ mate - Sharon Osbourne. She has since admitted things were a little awkward with Louis over their history at first, but they put it all aside for the sake of the show. (credit:ITV)
2012 - Cheryl Calls Louis A Rubbish Manager(03 of10)

After leaving ‘X Factor’ in 2011, Cheryl hit out at Louis during an interview about the early days of Girls Aloud, alleging that he “never managed” Girls Aloud, but had no problems “taking the cheque” at the end of it all. (credit:Mark Cuthbert via Getty Images)
2012 - I'm A Better Manager Than She Is A Singer(04 of10)

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)

After a lot of back and forth between the pair, Cheryl screen-grabbed a text that she’d been sent by Louis calling for a truce, which she then uploaded online.

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...
