NBC confirms 2013-14 casting for 'The Voice'

LOS ANGELES, May 17 (UPI) -- Christina Aguilera, CeeLo Green, Adam Levine and Blake Shelton are to serve as coaches on America's "The Voice" this fall, NBC confirmed Friday.

Shakira and Usher will join the panel alongside Levine and Shelton for the spring edition of the singing competition series.

Carson Daly will return as host for both cycles.

The casting announcement was made Friday by Paul Telegdy, NBC's president of alternative and late night programming.

"We locked in a plan several months ago to have the outstanding Christina Aguilera and CeeLo Green rejoin Blake and Adam for cycle 5, and we're pleased to announce that the original four coaches are going to be back together in the fall," said Telegdy in a statement. "They're the reason this show was launched so strong for the first three cycles and we owe them a debt of gratitude. And after careful consideration of everyone's schedules for next spring, we are excited to be returning the current cycle of judges -- Shakira and Usher along with Blake and Adam -- for cycle 6, which will premiere after the Winter Olympics."

"We're very fortunate to have these six incredible artists to weave in and out of the show as their performing and recording schedules permit," NBC Entertainment Chairman Robert Greenblatt said. "The show has taken off largely due to the rapport and commitment of these great coaches, in addition to the expert hosting of Carson Daly."

"I am so thrilled that our 'Voice' family has grown from four coaches to six," said executive producer Mark Burnett. "This show thrives on the ability of our coaches to continue to balance their enormous music careers with working on 'The Voice' to coach some of the best undiscovered talent in America. The coaching panel of Christina, CeeLo, Adam and Blake was at the heart of this show in its first three seasons and we are so lucky to have found equal success with Shakira and Usher in Season 4. Our best seasons are ahead of us."
