The 'Poison' hitmaker admits she and Lewis Hamilton have to "fight" to keep their five-year romance on track because they spend so much time apart.

She said: "It is tough. It's challenging and it makes things interesting, but it works. You have to fight for it."

Nicole recently moved to the UK to be a judge on 'The X Factor' and though she was initially homesick, she has now settled in well.

She told more! magazine: "For the first couple of days I was homesick, but I'm starting to find I'm fitting in quite well at being a Londoner.

"I love the people here, so that's really helped. And I've made my place a little bit more cosy with fairy lights and candles and yummy blankets."

The brunette beauty also thinks people have an idea of her that is very different from her real personality.

She said: "I think it's natural people would have misconceptions about me - they've seen me in the Pussycat Dolls and in my music videos, when I'm this sexy, fierce girl. And there is a side of me like that - I've got my Sasha Fierce in me. I've always had that.

"But then everyday I'm just a normal girl. I'm a goofball. I have a sense of humour and people don't always get to see that."
