During a stop on her "Circus" tour in Connecticut on Saturday night, a fan, 20-year-old Kyle King, jumped onstage and rushed a confused and terrified Britney Spears (2:15 mark) before getting hauled away by security. And yet, even though she was standing before thousands of fans, no one heard her cries for help.

A clearly shaken Spears screamed and frantically waved her arms as King approached her onstage at Connecticut's Mohegan Sun Arena.

Shockingly - or not - the notorious lip-syncher's mic didn't pick up her cries for help as King was grabbed by a back-up dancer and escorted offstage. (Source)

I guess Britney's tour managers could only take so many My Pussy's Hanging Outs or Merry Christmases before her mic rights were revoked for good. That's why having a microphone is a privilege, not a right. Or so I've been told anyway, after having forcibly taken my leave of more than a few bars on karaoke night.
