Nicole Scherzinger has 'sacrificed' her life for her career

Nicole Scherzinger has "sacrificed" her life for her career because she is nearing 40 years old and isn't married and doesn't have children.

The 38-year-old singer songwriter - who has recently returned to judge the popular talent show 'The X Factor' this year after leaving the show two years ago - has admitted she feels she has "missed out on life" because of her busy work schedule.

Speaking about her life and regrets, the brunette beauty - who is currently dating tennis ace Grigor Dimitrov - told The Mirror Online: "Look at me? I'm not married and I ain't got no kids yet. I'm still like 'let's go'.

"Of course work has come at a sacrifice. I've missed out on life."

But Nicole - who broke up with her former beau and Formula One champion Lewis Hamilton last year after seven years of dating on and off - has revealed her fellow panellist and music mogul Simon Cowell regularly makes jokes about their break-up, which Nicole doesn't take to heart.

Speaking about Simon's suggestion to dedicate Nicole's hit 'run' to her ex, she explained: "I'm quite light-hearted with all that stuff."

Meanwhile the former Pussycat Dolls band member - who is mentoring the Boys in this year's show - has admitted she believes she has got the winner in her group,a lthough she fears Sharon Osbourne and the Overs may give her a run for her money.

Speaking previously, the 'Right There' hitmaker said: "My strongest competition is Mrs O's category, which is the Overs - they have some really strong, heavy hitters and big voices. People who are really experienced.

"[But] I definitely think I could possibly have the winner here!" Before adding, "I think I have at least one or two stars."

And the former Pussycat Dolls band member - who will whittle down her category to three on Sunday - has admitted the judges' houses is her "least favourite part" of filming 'The X Factor'.

She explained: "This is my least favourite part. This is where I forget the gorgeous view and I'm dreading having to send more than half of my boys home."
