Cheryl Cole has said the unthinkable and revealed that music moghul Simon Cowell is ‘not always right.’

“You know what?” the 26-year-old told Top of the Pops magazine. “I’ve always had a little soft spot for Simon. I’ve always respected his honesty.

“I do tell him if I disagree with him though and I’m not scared to tell him my opinion. He’s not always right.”

Cheryl also talked about the issue of plastic surgery and refused to rule it out for the future.

“I’ve got nothing against cosmetic surgery,” she said. “I mean, if someone hasn’t got any boobs and having them done is going to make them a happier, more confident person, then go for it.

“I wouldn’t deny it if I had cosmetic surgery. I wouldn’t just come out with big boobs and say: ‘No, I haven’t had an operation!’ I think imperfections are sexy anyway, I honestly do.

“If everyone looked perfect with a perfect face and perfect boobs, it wouldn’t be sexy as it’s not real life.”
