The 31-year-old insisted she would never pose nude, but she doesn't judge reality star Kim, 34, for doing so.
CHERYL FERNANDEZ-VERSINI SLAMS NADINE COYLE: "SHE'S FULL OF SH*T!"
Speaking to The Sun, Cheryl said: "I don't think it's real. I'll refrain from passing judgement because each to their own.
"But I would never do it. I could never. I could never.
"I can't even get changed in front of my stylist who I've had for years. Just no."
While the former Girls Aloud star will definitely not be stripping off for the camera any time soon, she did tease that next year could be when she and husband Jean-Bernard start a family – which would mean quitting The X Factor.
She said: "You couldn't do them both. Next year is going to have to be the time where I reflect on what I've done and think about what I want to do."
Meanwhile, following the backlash she received for 'miming' on the show a few weeks back, Cheryl performed on Children In Need last night and there was no doubt it was live.
But the former Girls Aloud star still didn't please everyone. Twitter users blasted her, with one writing: "Cheryl Fernandez-Versini CANNOT SING!!! That was a pathetic embarrassing performance last night. She should stick to miming."
Another wrote: "I wish Cheryl would stick to miming. It's far less offensive than her singing live."
Ouch. Watch the performance and let us know what you think.
