Ke$ha SLAMS Britney Spears For Lip-Syncing

Ke$ha claims to have helped Britney Spears write her songs before becoming famous in her own right (for hit single "TiK ToK," primarily) and now she is slamming Britney's lip-syncing ways.

"I don't think that's fair at all for people who are going to see the show," she told Scotland's Daily Record. "I think if you are going to be a singer, you should sing. If you are going to be a dancer, you should dance. If you are going to do a combination of the two, you should make it very clear when you are singing and very clear when you are dancing."

Throngs of disappointed fans stormed out of a Britney Spears lip-syncing concert in Australia last year.

"It's treating people as if they are too stupid to realize you are not actually singing," Ke$ha continued. "Sometimes it is hard to sing and dance at the same time, but I would rather be off and be real and genuine about it to my fans. I don't want to treat my fans like they are stupid...When I am singing, I may sound s--t sometimes, but at least you'll know I'm singing."
