Nicole Scherzinger says being famous is hard work

Nicole Scherzinger says being famous is hard work.

The Pussycat Dolls singer - who is currently dating British Formula 1 racing driver Lewis Hamilton - insists fans don't realise just how much effort goes into being a pop star.

She said: "It's not as glamourous as people think. It has its ups and downs. There can be a lot of intrusion into your private life, but I want to be known for my music.

"It's not partying all the time - sometimes when I get the chance I am too tired to party! People don't see the work that goes in to touring but it's definitely worth it."

Despite being in a relationship with Lewis, Nicole thinks one of the strangest things about fame is the number of different men she is romantically linked with.

The 30-year-old star - who was recently reported to be dating Black Eyed Peas star will.i.am after allegedly being spotted smooching with him at Los Angeles' Opera nightclub - added to MTV: "I find that sort of thing funny. That was the funniest thing when someone told me I was supposed to be dating Will. He is like my brother, I don't know when the last time I saw him was. He has been on tour."

Although Nicole is remaining coy about her relationship with 22-year-old Lewis, she knows what qualities her perfect man should have.

The 'Don't Cha' singer - who first met Lewis at the MTV Europe Music Awards in Munich, Germany, last November - said: "I look for someone with a good heart. Someone who is confident and successful and goes after what he wants. I love a guy with a great sense of humour."
