Do friendships get any realer than that of Blake Shelton and Adam Levine?

Blake gets funny in a new interview with the Tennessean, revealing while his fellow coach on The Voice is “one of the best friends” he has, but he “still want[s] to kill him sometimes.”

“I know every trick to get under his skin,” Blake says of Adam, who can dish the tricks himself. “Until someone is crying, it doesn’t stop.”

At times, the “Every Time I Hear That Song” singer feels as if he and the Maroon 5 front man are in high school.

“We’re those two guys you knew in high school where we have this bond that is unexplainable. It brings out the best and worst in both of us. It truly is an explosive relationship.”
