The 38-year-old singer thinks becoming a father to little Eric - who he has with girlfriend Lauren Silverman - has completely changed the music mogul and she enjoys spending time with him on 'The X Factor', particularly when his "sweet" offspring comes to visit the set.

She said: "[Simon] has changed. He's on the soft side. I find myself agreeing with him...that's not normal.

"Eric is so sweet, he speaks such proper English it cracks me up. I feel like his IQ is higher than mine. It's great to see Simon so happy."

While Nicole is enjoying life back as a judge on 'The X Factor' in the UK, she suffered a professional disappointment earlier this year when she lost out on the role of C.J. Parker to Kelly Rohrbach in the upcoming 'Baywatch' film.

She told the upcoming November issue of Britain's Glamour magazine: "I started this year working out every day, motivated to get my butt in shape because I was determined I was gonna be the new 'Baywatch girl'. I was hell-bent, I'm an ocean angel, I love it.

"I was devastated."

She jokingly added: "What is my year, what is my life, if I'm not in 'Baywatch'?!"

After a lengthy on/off relationship with Lewis Hamilton, Nicole has been dating tennis player Grigor Dimitrov, 25, for the last year, and couldn't be happier.

She said: "I am happy. I'm in a really good, solid, more balanced place in my life. I've grown a lot as a woman.

"My grandma always used to say, to find the person you wanna marry, you have to find the person you wanna work on your relationship with for the rest of your life. That's the key word: work."

But the 'Poison' hitmaker was furious when a night out with her friend Calvin Harris sparked romance rumours in July after they left a nightclub arm-in-arm.

She said: "It was all, 'She's the biggest cheater', I'm like, excuse me? I was walking on cobblestones, almost fell, grabbed him, two frames and that was it. It's ridiculous."
