London, Aug 30 - 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.
