EXCLUSIVE: Blake Shelton Says Beyonce's Country Critics Can 'Kiss That A**'

Not that Bey needs backup, but Blake is a fan of 'Daddy Lessons.'

It's not like Beyonce really needs backup, but Blake Shelton is all about Lemonade and the country-tinged "Daddy Lessons."

And in typical Blake fashion, he's got a message for the haters.

"People that criticize can kiss my a**. That's what I say," the country superstar told ET backstage at The Voice on Monday. "I can't believe people that don't contribute to music that criticize music, it just blows my mind and Beyonce -- tell them to kiss that a**, is what I would do."

We can always count on Blake to tell us how he really feels, and he had an equally entertaining take on his future Voice co-star, Miley Cyrus.

"I've known her dad for years, and so it's like -- 'I'm gonna call your dad! I will tell your dad what an a**hole you're being right now, so you better settle down, missy!'" he joked.

The duo hit it off in an earlier episode of The Voice, when Miley lent her expertise as a mentor on the show. With Blake an outspoken hunter and Miley an outspoken vegan, the pair's tight-knit friendship seemed unexpected, to say the least.

"I can't imagine us ever having a problem," Blake said. "We completely understand each other, and just because she lives her life one way and I live my life one way doesn't mean we're not friends. Because, God, if that was the case, I wouldn't have -- especially in this town, Los Angeles -- everyone would hate me."

Miley will join Blake as a full-time coach on the next season of The Voice, alongside Adam Levine and Alicia Keys.

"To go from Hannah Montana to the Miley Cyrus that we know now, it's the craziest evolution maybe ever," Blake said of her career. "But I don't know that anybody can say she's made a wrong move. She's one of the biggest stars in the world and the numbers kinda speak for themselves. You can't do anything when you look at her career and the success she's had other than just go, 'Respect.'
