早前，布兰妮被指在小型演唱会上假唱，这已经令歌迷不满。日前，她在奥兰多的演唱会上再度出事，这次她继续对口型，期间CD多番跳线，令她出丑人前。
　　
请看外电相关报道：Britney Spears was left red-faced during a 14-minute concert in Florida when her backing tape skipped revealing once and for all the pop superstar is lip syncing her comeback.

The Toxic¹ singer was performing her fifth return show at Orlando's House of Blues² when the incident happened, forcing the singer to look away as technicians raced to get the tape back on track.

报道中的“lip sync”就是我们所说的“假唱”。“Lip sync”是“lip synchronization³”的缩写形式，指“to move the lips in synchronization with recorded speech or song”（口型与“原声大碟”同步），sync/ synchronization表示“同步”。

此外，在应用上，动词“lip sync”均可做及物和不及物动词，如“to lip sync the song 'Baby one more time'”，而“lip syncing”通常是其相应的名词形式。
