Ronson Dismisses Pussycat Dolls

US producer Mark Ronson is determined he will never work with The Pussycat Dolls, labelling the six-piece as "not genuine".

The New York producer has worked with everyone from Robbie Williams and Amy Winehouse to Christina Aguilera and Lily Allen.

So far he hasn't refused to work with anyone, but he insists he has standards.

He tells British magazine Star, "The main problem I have is with people I don't think are genuine - I wouldn't work with The Pussycat Dolls.

"But with most people, I would at least sit them down and have a chat."
