She was at pains not to hiss about any split rumours when in Melbourne for the Spring Racing Carnival in November, but sex kitten Ashley Roberts has come clean and said she has quit the Pussycat Dolls. The Dolls have been surrounded by split rumours for some time after reports of tension between the five girls. Whispers were the kittens were jealous of top cat Nicole Scherzinger's supposed special treatment and spent no time with her while touring Oz last year. Roberts has written on her website that she quit to pursue an acting career. "Yes, I have left the Pussycat Dolls, I love you all sooo much! I am so grateful to have the love and support of all of you," Roberts purred. There are now not many pussies left in the pride, with fellow doll Kimberley Wyatt also saying this week she was leaving because she "just couldn't do it any more". "Money and fame can't buy happiness," Wyatt said. This leaves the group, who lost member Jessica Sutta in January, with two remaining Dolls, Scherzinger and Melody Thornton.
