"There are very few musical artists as accomplished and talented as Jewel. Her addition to 'The Sing-Off'' judges panel, along with our stellar team of Shawn Stockman and Ben Folds, raises the showmanship of the series up another notch," Paul Telegdy, NBC's president of alternative and late night programming, said in a statement Tuesday. "The musical credentials of Nick Lachey are extraordinary and his continued contributions to the show as host remain a huge asset."
"I am so thrilled to welcome Jewel to our expert musical panel. Jewel is one of America's greatest singer-songwriters and is an amazing storyteller. In company with the incredible talent of Ben Folds, Shawn Stockman and Nick Lachey this season of 'The Sing-Off' is sure to be its best yet," said executive producer Mark Burnett.
The fresh run of episodes is to air over several nights later this year. "The Sing-Off" originally premiered in December 2009 as a five-night event and became a weekly series in 2011.
The winner of the a cappella singing competition will walk away with a recording contract and $100,000.
