Nicole Scherzinger has said that her career success has come at a price - because she has "no kids yet".
The ex-Pussycat Doll, 38, is back on the panel of The X Factor this year.
She told the Sunday Mirror that she had made sacrifices in her personal life.
"Look at me? I'm not married and I ain't got no kids yet. Of course work has come at a sacrifice. I've missed out on life," she said.
But Nicole said that she had not expected to have children by now.
"I see a vision of what I want as an artist.
"Now I'm going to the top of that mountain. When I get there, then I'll have time for a family, and kids," she said.
"It's a sacrifice when you put your heart into a job. Relationships suffer."
The singer turned down starring in Andrew Lloyd Webber's Cats on Broadway - after having the lead in the London cast - to return to the ITV talent show.
Broadway is something she still wants to do, but she says the timing was not right and The X Factor freed her up to work more on her singing.
She was with Formula One ace Lewis Hamilton, 31, for seven years.
She is currently dating tennis star Grigor Dimitrov, 25.
"He's a fan of The X Factor," Scherzinger added. "He's very supportive."
Nicole is mentoring the boys in X Factor this year.
Simon Cowell is looking after the overs, Louis Walsh has the groups and the girls will be coached by Sharon Osbourne.
