For those who shared the Aussies’ outrage over Britney Spears, here’s a new TV show for you: The Sing-Off, a competition you can not sync your lips into.
Hosted by Nick Lachey, the four-night NBC series premiering Dec. 14 features eight singing groups vying for an Epic Records/Sony Recording contract, and the only instruments allowed will be their own voices.
“There is nowhere to hide when you’re doing an a cappella song,” Lachey, the former member of 98 Degrees (and, he reveals, a barbershop quartet before that), tells PEOPLE. “There s no band behind you and dubbing. It’s just you. It s just them naked on stage and what they have done to prepare is what will show through in that moment.” – Jennifer Garcia and Mike Fleeman
