Nicole Scherzinger's romance with racing driver Lewis Hamilton is reportedly on the rocks

The Pussycat Dolls singer has been dating the British Formula One ace for nearly three years, but they have reportedly not seen each other in three weeks and shelved plans to spend Christmas together.

A source told the Daily Mirror newspaper: "Lewis and Nicole have had a few problems for a while now. They love each other dearly but have incredibly busy schedules.

"Nicole was in London last week and was desperate to hook up with Lewis but she was busy in the studio while he is on a European training camp and couldn't come back.

Lewis and Nicole have had a few problems for a while now. They love each other dearly but have incredibly busy schedules.

"Hopefully after a month apart, they will come to their senses and give things another go."

Despite the claims, a spokesperson for Lewis insisted the couple are "perfectly fine".

Meanwhile, Nicole recorded the theme song to forthcoming musical 'Love Never Dies' - the sequel to the hugely popular 'Phantom of the Opera', by composer Lord Andrew Lloyd Webber - while in London.

A source said: "Andrew is a huge fan of Nicole and her voice. He has always said she could become one of the biggest stars on the planet with the right songs."

Pussycat Dolls split in row over Scherzinger?

American pop girls group The Pussycat Dolls has called it a day, amid jealous rows over the rising profile of lead singer Nicole Scherzinger, girlfriend of British motor racing ace Lewis Hamilton.

Band member Kimberly Wyatt confirmed Saturday that the group were taking a long break to consider their future, fuelling speculation that it's all over for the band who formed in LA in 2003, reports mirror.co.uk.

"The girls and I have just finished our huge world tour and are taking a break from the band and doing our own thing... We're all concentrating on our own projects and deciding what the future will hold," said Wyatt.

Rumours are rife that tensions have been mounting in the Pussycat camp for several months. The five-member ensemble has been divided by jealousy over the star treatment being meted out to their lead singer.

Earlier this year Scherzinger, 31, was singled out for special mention on the group's "Slumdog Millionaire" single "Jai jo", which was billed as The Pussycat Dolls featuring Nicole Scherzinger.
