The two beauties are not strangers, having been spotted hanging out at a Kanye West concert together and tweeting each other sisterly words of support over the years.
But it sounds like Cheryl’s still trying to get her head around her pal’s recent nude shoot. And she certainly something to say about that famous asset of hers.
‘I don’t think it’s real,’ the 31-year-old told The Sun during rehearsals for Children In Need.
‘l refrain from judgement because each to their own. But I would never do it. I could never. I could never. I could never.’
But it seems the X Factor judge’s shock is perhaps more down to shyness on her own part, as Cheryl continues:
‘I can’t even get changed in front of my stylist who I’ve had for years. Just no.’
Ever since the photos emerged last week, there’s been much chat over whether Kim’s insanely bootilicious rear had been tampered with.
And Cheryl’s comments come just as editor of Paper Magazine, Kim Hastreiter, sets the record straight.
‘Of course it was Photoshopped,’ Hastreiter told DigiDay of the cover.
‘Do you really think that you can open a bottle of champagne and get it to spray in a thin line over someone’s head and land perfectly in a glass sitting on that same person’s bottom?’
She added of the shoot: ‘Kim really adored the work of Jean-Paul Goude and was dying to work with him. We made the match and once we did, Kim needed no cajoling. It was like a dream shoot.’

‘In fact she arrived at the shoot totally excited and game to collaborate and do whatever it took to make the most amazing Break the Internet images possible. And they went there!’
