Sexy pop six-piece THE Pussycat Dolls has slammed reports they are on the verge of splitting up. The American group, who derived from the Los Angeles burlesque dance troupe, leaped to fame last year (05) with their huge hit DON'T CHA. Frontwoman Nicole Scherzinger's recent solo work with Sean Combs and opera star Vittorio Grigolo has fuelled speculation the girls are going their separate ways. However, a spokesman insists the girls are very much together.
