Jennifer Hudson is reportedly struggling as The Voice season 13's newbie.

According to a new report, the American Idol contestant turned actress first feuded pre-season with returning coach Miley Cyrus before later engaging in what is being described as an all-out war with veteran judge Blake Shelton.

“Blake straight up told Jennifer that she is an entitled b***h and that he’s never worked with someone so difficult to be around,” an on-set source told Radar Online on October 5. “He thinks that she is trying to steal the spotlight, which she is. But it is creating a lot of tension on and off-camera.”

Hudson joined the cast of The Voice earlier this year after Gwen Stefani opted to take the season off. However, as fans of the singer will recall, Hudson isn't completely knew to the series. In fact, she starred as a judge on the series' U.K. version just a short time ago and already, she seems to have pulled in front of her fellow judges, including Blake Shelton, Miley Cyrus, and Adam Levine.

“The fact that Jennifer is scoring such amazing talent to be on her team drives Blake insane," the source continued. "The two of them are bickering non-stop and he has lost his temper several times already. But she knows that he cannot stand her and that makes her push his buttons even more."

“She is racking up enemies like no other judge before,” the production source added. “She had several contestants crying backstage after blind auditions because of her commentary.”

To see more of Jennifer Hudson, Blake Shelton, Adam Levine, and Miley Cyrus, tune into new episodes of The Voice season 13 on Monday and Tuesday nights at 8 p.m. on NBC.
