"I'm delighted to be a part of such a great show, it's just what the holidays are all about - family-fun and giving," said Menounos. "I use to be in a choir myself growing up and I can't wait to see these hometown choirs come to life on stage."
Clash of the Choirs will begin with five celebrities -- former Newlyweds: Nick & Jessica co-star Nick Lachey; Nashville Star judge Blake Shelton; Michael Bolton; Patti LaBelle; and Kelly Rowland -- traveling back to their hometowns to assemble an amateur singing group consisting of everyday people.
The hometown choirs will then compete against one another in-front of a live studio and home-viewing audience, tackling a variety of musical genres that range from pop, rock and gospel to holiday classics and current hits.
Home viewers will be able to vote via phone, text messaging or the Internet to determine which choir wins the competition. The winning choir -- as well as the celebrity that organized them as a group -- will receive the opportunity to select a prize that will help their hometown.
