She's All Talk! 'The Voice' Coaches 'Frustrated' With Chatty Kelly Clarkson

Kelly Clarkson has quickly become a fan-favorite judge during her short time coaching on NBC's hit singing reality competition show, The Voice!

But RadarOnline.com has exclusively learned that the 36-year-old "Break Away" singer isn't getting the same love from her co-stars as she is from viewers — because she can't shut up!

"The other coaches cannot get a word in sometimes because Kelly literally talks non-stop, but she can't help it," an on-set source told RadarOnline.com. "Although the audience doesn't seem to mind, it is getting quite frustrating for the other judges."

"Kelly is a powerhouse and she is such an amazing addition to the cast, but the higher-ups have had to have a chat with her to ask her to bring it down just a notch," the source added.

Veteran coach Blake Shelton, 41, let his feelings be known during a recent episode when he noted on-air: "You know, Kelly talks a lot. I'm starting to feel a little bit sorry for Adam now, because Kelly talks as much as Miley Cyrus, and Adam's been sitting by Miley in the seasons past, and I don't know how he breathes."

So how does coach Adam Levine, 39, really feel about his talkative co-star Clarkson?

"Adam is slightly bothered only because he is the one that is used to being in control and running the conversation amongst the judges," the insider told RadarOnline.com. "Now they clearly have a new sheriff in town."

As RadarOnline.com previously reported, Clarkson has already been asked to return to The Voice after the show's ratings demolished those of its rival, the revamped ABC reality singing competition American Idol .
