The “never -ending” feud among “The Voice” judges appears to invade the show as Miley Cyrus continues to slam Adam Levine and this is while she is drunk.

The “Wrecking Ball”singer was a “little” drunk while promoting the show with another new coach, Alicia Keys. According to Mail Online, Cyrus told the audience that “They’re all a little drunk, but that’s okay, so are we.”

As for her beef with the Maroon 5 singer, Radar Online reports that they are still annoyed at each other. “Adam and Miley were non-stop bickering during their last taping together,” the insider revealed. “He nitpicks almost every single thing she says. Adam seems to find Miley to be extremely loud-mouthed and absolutely annoying!”

Probably, their feud was rooted when Cyrus was one of “The Voice” key adviser last year and the fact that both have a “short attention spans“, as per Us Weekly. “Adam would get agitated when Miley would interrupt him, and she enjoyed getting under his skin,” another source said.

While they cannot stand the sight of each other, other coaches are also speculated to be having an on-set war. Christian Aguilera reportedly hates “The Voice” lovebirds Blake Shelton and Gwen Stefani.

The feud allegedly started when the couple announced their relationship publicly that magnets more viewers. According to a previous report, Aguilera was threatened that Shelton and Stefani have been stealing the spotlight from her because of their mushy PDA’s.

And for that, the “Beautiful” singer unleashed her diva attitude and threw tantrums on the set. She allegedly said that the “No Doubt” singer does not deserve to be on the show because she has “no vocal talent.”

Even the pair has been rumoured to be having explosive fights as well, but it was later found out that Stefani was the one having an argument with the execs because they did not pick her to be a permanent judge on “The Voice.”
