Boyz II Men Caught Lip Syncing During Christmas TV SpecialNote to musicians performing on live television: Beware the lure of lip syncing because eventually you may get caught. Boyz II Men got busted using a pre-recorded track during their mini set on Tuesday's live NBC special at the tree lighting ceremony in Rockefeller Center.

The R&B group was exposed after an awkward transition to the next act. After Boyz II Men finished performing 'This Christmas,' the show transitioned to a duet by pop singer Charice and pianist David Foster, who were supposed to sing 'Jingle Bell Rock.' But then the Boyz II Men song replayed for more than 12 seconds. The music turned off and on again as one could tell the sound engineers were struggling behind the set. Watch, via Mediaite, after the jump.
