Jennifer Hudson 'Angry' Over Surprise New 'The Voice' Coach Kelsea Ballerini

Jennifer Hudson is raising her angry voice about a new coach on her TV show!

NBC's The Voice is adding a fifth coach, country star Kelsea Ballerini, to the show this season and RadarOnline.com has exclusively learned that the move has outraged diva judge Jennifer Hudson.

As fans know, Ballerini, 25, will be joining current judges Adam Levine, 39, Blake Shelton, 42, Kelly Clarkson, 36, and Hudson, 37.

According to a source close to production, "They added this element to the show because it gives the hopefuls another chance."

"Basically, Kelsea will mentor six contestants during the comeback stage that were knocked off in the blind auditions."

And while producers feel that the new addition will be "great" for the show, Hudson does not see it that way, according to the source.

"Kelsea was picked by Blake who insisted that they choose a country star," the insider told RadarOnline.com.

"While Kelly and Kelsea get along great, the two are already at odds with Jennifer who is like her own entity."

"Jennifer doesn't really get along with anyone and she is continuing to cause a disturbance. She is also very opinionated when it came to the new hire," the source said.

Season 15 of The Voice premieres on Monday, Sept. 24 at 8 p.m. EST.
