Britney Spears responded to the lip sync rumors that have been going around for years!
In an interview with an Israeli television network, she said: "A lot of people think that I don't sing live. Because I'm dancing so much I do have a little bit of playback, but it’s a mixture of my voice and the playback .It really angers me, because I am busting my butt out there and singing at the same time and nobody ever really gives me credit for it."
Here's a video of her denying/confirming lip sync rumors in the past.
Hey, lip syncing or not...she puts on one hell of a show! I couldn't dance like that (let alone sing) for over an hour!
