Nicole Scherzinger's former bandmate, Kaya Jone, has lashed out at The X Factor star and refutes her claims that the rest of The Pussycat Dolls were just “window dressing”.

In an upcoming VH1 Behind The Music Special Scherzinger claims that she did 95% of the singing in The Pussycat Dolls and that the rest of the group did not record any vocals for their albums.

While Kaya did not deny these claims, she insisted that rest of the girls were heavily in the band, and not just there to look pretty.

She told ''There was a lot more going on behind the scenes. Nicole was always someone who wanted to be in the spotlight and would do pretty much anything to get it.

''To call the other girls in the Pussycat Dolls 'window dressings' is a bit far-fetched ... every girl in the group was talented.''

In a clip released for the documentary 34-year-old Scherzinger claims that her fellow bandmates - Melody Thornton, 28, Ashley Roberts, 31, Kimberly Wyatt, 30, Jessica Sutta, 30, and Carmit Bachar, 38 – had never even heard their album PCD until days before it was released.

Scherzinger said: ''I hope I don't get in trouble for the stuff that I say but I'll never forget I finished the album, PCD, and [executive producer] Ron [Fair] and I brought the girls into the studio and we played it for them. It was the first time they'd ever heard the music.

''Do you understand what I'm saying? We played the album for the Pussycat Dolls. It was the first time they'd ever heard the songs.''

Fair backs up Scherzinger, admitting she did more singing than her bandmates. He said: ''Melody sang a bit here and there, but the records were Nicole, with the exception of an occasional ad-lib.''
