Singer Sara Bareilles has signed on to Nick Lachey's reality TV competition show as a celebrity judge.
The hitmaker will now join fellow singers Ben Folds and Boyz II Men star Shawn Stockman on the panel of NBC TV's "The Sing-Off" this autumn.
The show sets out to find the best vocal groups who can perform without accompanying music.
In a statement released to Entertainment Weekly, she says, "A cappella music is very near and dear to my heart, and I have been a huge fan of the show from the beginning.
"I love the opportunity to be a part of something that celebrates a genre of music that I just adore and believe in. I can't wait for it to start."
The show will return on September 19.
