Nicole Scherzinger has admitted prioritising her career has made her "lonely".
The 39-year-old singer has said she finds it "hard" to balance her private life with her hectic career as a musician and judge on UK talent show 'The X Factor', and admits a constant life on the road has left her desperate for some company.
She said: "Anybody who is successful in what they do is making sacrifices. It's juggling and finding the balance. I've absolutely missed out on things in life. It is hard, I'm not going to lie. It can be lonely. I'm always on the road, I'm always by myself. I think anybody in this industry feels lonely."
Nicole is rumoured to be romancing tennis hunk Grigor Dimitrov, but the pair have not been pictured since July this year, which has led to speculation of a split.
But the former Pussycat Dolls singer isn't too disheartened by her lonely love life, as she admits she has a "great support system" of friends to keep her on the right track.
Speaking to the Daily Star Sunday newspaper, she said: "I would say it generally gets harder to find the balance the older you get. Timing is everything. When things are aligned then it will be easier. There's always a sacrifice to be made but it's either worth it or not.
"For me, I'm very spiritual. What guides me the most is my purpose. Everything in it's own time and to start on track with my purpose.
"I've got a great support system around me, a select group of friends. I don't have quantity, that's for sure, I have quality. I've always been more introverted. Gratitude is key."
Previously, the 'Don't Hold Your Breath' singer admitted fame had made her relationships "suffer", as she hasn't settled down to start a family.
She said: "Relationships suffer. Look at me. I'm not married and I haven't got kids yet."
