Britney Spears : Diclaimer on Show Tickets for Lip Sync ?

Britney is now touring Australia with her “Circus” show. Local officials want to force her to put a disclaimer on her show tickets stating she’s not performing live. Because if you’re just a lip sync machine the show is nothing more than a pre-recorded video clip with the presence of the artist during the play, not a performance. To lip sync or not to lip sync ! But wait a minute… is Britney the only star around to fake it ? :-)
