Britney Spears mimes AGAIN on U.S. TV as she performs same routine that bombed on X Factor

After an onslaught of criticism of her identical mimed performances in Europe last week, you'd expect Britney Spears to re-work her latest performance.

But as she appeared on TV in her native U.S. today, it appeared the backlash had failed to move the singer as she performed the same set yet again.

Singing songs from her new album Circus in New York City today, Britney writhed on stage with her dancers, doing the same moves, wearing the same outfits, with the same pyrotechnics.
