Spears is currently on her Piece of Me tour overseas. Earlier this week, the pop star addressed lip-syncing accusations, saying that "it really pisses me off" that people don't believe that she sings live.
"A lot of people think that I don’t sing live. I usually, because I’m dancing so much, I do have a little bit of playback, but there’s a mixture of my voice and the playback," she said during an interview with an Israeli TV show. "It really pisses me off because I am busting my a** out there and singing at the same time and nobody ever really gives me credit for it, you know?"
