"The Voice" finale taps Rihanna, Kelly Clarkson, Bruno Mars and the Killers

LOS ANGELES (TheWrap.com) - The season finale of "The Voice" has enlisted some high-profile talent to help send the show's third cycle off with a bang.

Rihanna, Kelly Clarkson, Bruno Mars and The Killers have been tapped to perform on the two-hour extravaganza, which will culminate with the crowning of a new champion, NBC said Wednesday.

An additional special guest will be named at a later date, the network added.

Rihanna will perform her song "Diamonds," while "American Idol" alum Clarkson - who has served as a guest mentor on the show, as well as hosting the rival singing competition "Duets" - is set to sing "Catch My Breath."

The Killers, meanwhile, will play their single "Runaways," and Mars will debut the song "When I Was Your Man" from his sophomore album "Unorthodox Jukebox," which was released Tuesday.

The season finale of "The Voice" will air live on December 18 at 8 p.m.
