NBC decided in March to bring back its a cappella contest show The Sing-Off, and now the network has announced that Jewel will be replacing judge Sara Bareillis. She'll join returning judges Ben Folds and Boyz II Men's Shawn Stockman, and host Nick Lachey will also be back. Musically, Jewel is qualified to judge a televised singing show. But she hosted and judged Bravo's total dud Platinum Hit in 2011, and she was borderline catatonic and not at all insightful. Kick it up a notch, Jewel! The best part of The Sing-Off is its judging panel.
