Although the 'X Factor' judges get on well, Nicole, 38, was not impressed when Louis, 64, quipped that she had undergone breast enhancement surgery.

She told The Sunday People: "I said to Louis I'm like a fine wine, I just get better with age. When the time comes, maybe I'll experiment with Botox. I just want to look like JLo. I mean how old is Jennifer now? And she's the best she's ever looked.

"Louis pushes his luck, but I can handle him. I've known all of them for a long time, so you can be cheeky and occasionally push it but we never take it personally."

And despite being annoyed over Louis's jibe, Nicole insisted the pair are actually very good friends.

She said: "A lot of the time, Louis is the one to lift me up. Some days he gives me a pep talk. We're real friends behind the scenes."

And Nicole admitted she would be happy to return to the ITV show next year, if Simon Cowell offers a good enough incentive.

She explained: "At the start of this year, I didn't know what I'd be ¬doing but you've got to be open in this business. Maybe I'd be open to coming back to 'X Factor'.

"We'll see how hard Simon tries to persuade me!"

And with her career going well, the brunette beauty recently admitted she is also in a "very good place" in her personal life.

She shared: "I'm at a very good place now. I'm really happy. I don't feel like there is any wall up or any tension or awkwardness. But that's what's so great with time and life and experience. What doesn't break you or doesn't kill you really only makes you stronger.

"I wasn't shying away from anything. But I'm not taking any low digs or slaps at my past relationship because that's just not who I am. Music speaks for itself and it's open to interpretation for everyone. But everything I sing, I sing it from my piece of truth."
