[NEWS] FIND OUT WHAT NBC'S 'THE VOICE' COACHES, CHRISTINA & CEE LO HAVE NICKNAMED EACH OTHER

"Extra's" Terri Seymour caught up with "The Voice's" Christina Aguilera and fellow mentors Cee Lo Green, Adam Levine and host Carson Daly. The new singing competition features contestants who are judged purely on their voice in a blind audition.

Christina and her co-stars have already coined nicknames for one another with Cee Lo calling Aguilera "Mommy Dearest." Christina turned to Cee Lo and laughed, "He's Dirty Uncle"! He's so excited when his chair turns around and there's something he likes on the other side." The chair she is referring to automatically swivels to face the contestant if the coach pushes a button signaling he/she is impressed with the person's voice.

Cee Lo revealed, "There have been a few occasions where the beauty and the talent both kind of matched up." Carson Daly added, "He [Cee Lo] wears the glasses and goes, 'hey baby girl.' That's his thing -- 'hey baby girl.'"

Play it by ear when "The Voice" comes to NBC on April 26.
