Although you may see Adam Levine and Blake Shelton bicker on the hit show "The Voice" in real life the pair are good friends. Recently the country star sat down with Men's Journal about why he becomes so frustrated with his fellow judge.

Shelton told the magazine that Levine's healthy lifestyle choices annoy him. He said, "I get frustrated with Adam because, to me, rock stars are supposed to be drunk all the time.

"But he's very healthy. He takes care of himself. And it drives me crazy, because I want him to be more like me. Drunk all the time."

Apparently the healthy choices of the Maroon 5 lead singer are the source of the pair's constant disagreements.

So does that really mean that Blake Shelton is drunk all the time? According to his mother the answer is a big no.

She told the magazine, "He likes to make people think he's drunk, but I've never seen that boy drunk in my life."

According to UPI, even though the two have their spats Adam Levine had nothing but kind words to say about Shelton, "The guy is just pure positive energy."

"He has this kind of punk-rock mentality, where he's not afraid to speak his mind, not afraid to say the wrong thing. It's a huge part of his success: What you get is different than what you're expecting."

However, Levine is not the only one on the show making healthy lifestyle choices, recently Shelton made the switch to a healthier drink because of wife Miranda Lambert.

In Men's Journal it was revealed that the "Boys Round Here" singer is a fan of diet cherry 7-Up but when he was seen mixing together a concoction he explained that his wife said it was healthier for him and according to Shelton you don't want to cross her.

"I don't give her too much sh**, that's like poking a bear," he said referring to his wife's personality.

"She's as lovable as can be - until you cross her. She'll go from zero to 100 real quick. If Miranda has an inkling you're saying something hardass to her, it's gonna be a problem."
