"Idol" lips synch this

Justin Guarini

knows lip-synching when he sees it.

Last week the former “American Idol” contestant opined that he thought contestants were lip-synching on group numbers.

And he was right.

"Due to extensive choreography and to balance their voices with open mics against a screaming audience, the Idols do sing along to their own prerecorded vocal track during the group performances only," a representative for the show told

The New York Times

this week, emphasizing that all of the solo performances were 100 percent live.

They’re singing to their own voices. No harm, no foul.

Just “Idol” chatter.
