Lip-Synch Britney in Britain?


Britney Spears 'performed' in the UK for the first time in five years when she appeared on the "X-Factor" this weekend -- but did she lip-synch?

That's the question on everyone's mind after the Britster performed her hit "Womanizer" as a reported 13 million people watched at home.

Brit's alleged lip-synching didn't appear to bother judge Simon Cowell -- the acid-tongued judge gave the recovering pop princess a standing ovation.
