The true music fans will jknow that this performance is lip-synced because the very few times she performs live (X Factor 75% live, Alan Carr's Chatty Man 50% live) he hand movements are destinct and you can hear her breathing heavily as she reaches the high notes. This definately is not live, her breathing is so not matching the notes reached.

Jeremimi - you chat shit. it is impossible for any artist to sound EXCATLY like their recording unless they're at the top of their game. Take Whitney, look at how different her performance of "I didn't know my own strength" was to the actual recorded version on the album. Duh!

By insulting whitney and by calling us haterz you so called "mariah fans" are just making yourselves look dumb and you reduce mariah's credibility because you make it seem like her fans are thick (as well as deaf). be realistic and accept critism. for f*cks sake mimi is a divi she brought her own toilet paper to the studios for this performance (see digitalspy).

Mimi cannot sing live well any more. FULL STOP!

(next you mariah fans will be telling us that Cassie can outsing Leona, Cheryl Cole can out-sing Alesha Dixon) jeeze!
