Nicole Scherzinger no longer "has a life".

The Pussycat Dolls singer - who is dating racing driver Lewis Hamilton - admits that all she can currently focus on is her training for reality TV contest 'Dancing With The Stars'.

She said: "I actually don't have a life anymore. All I do is dance and sleep when I can. Even then I dream about dancing. I don't know what else is happening with anything else in my life right now."

Nicole and her professional partner Derek Hough have topped the show leaderboard almost every week but she admits her "perfectionist" attitude can be frustrating for the dancer.

She said: "I always feel like I'm rehearsing. I'm a workaholic. But you've got to let go and trust and enjoy!

"I'm a real perfectionist. Derek sometimes gets frustrated, and it can hinder me sometimes.

"It's probably my biggest disadvantage. But as long as I can go out there, trust in the work and just have fun - that's what matters."
