The burlesque star and former wife of Marilyn Manson said that the Don't Cha hit-makers, led by Nicole Scherzinger, sanitized the dance form.
She said: "It's really great they decided to become a pop group and they've left the pseudo-burlesque alone.
"It drives me crazy when groups like the Pussycat Dolls try to sanitize and take away the sexual and nudity aspects of burlesque."
She added: "I'm sorry, but if you're not up there taking your clothes off and dancing around in pasties and a G-string, it's not burlesque.
"It can be cabaret, or it can be cute and funny and retro-showgirly, but it's not burlesque.
"They were strippers, and that's the way it was."
