Nick Lachey returns as the reality show's host.
Nick Lachey is returning to NBC's "The Sing-Off" for a fourth round. Additionally, Grammy nominee Jewel will join the singing competition series' recently announced fourth season as a judge alongside returning stars Shawn Stockman and Ben Folds, The Hollywood Reporter has learned.
Jewel replaces Sara Bareilles, who stepped in for Nicole Scherzinger in the show's third season.
"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," said Paul Telegdy, NBC's president of alternative and late-night programming. "The musical credentials of Nick Lachey are extraordinary and his continued contributions to the show as host remain a huge asset."
