AceShowbiz - Garth Brooks enjoys pranking Blake Shelton over his relationship with Gwen Stefani. "The Voice" coach, who recently released a duet with the husband of Trisha Yearwood, revealed his "Dive Bar" collaborator recently pranked him ahead of Blake's performance at Garth's concert at Albertsons Stadium at Boise State University in Idaho.

Speaking to ET Online after the concert on Friday night, July 19, the "God's country" hitmaker shared, "I got a text from my man here earlier that said, 'Hey, man, we got your dressing room set up for you.' And he sent me a picture and it was a paper that said 'Mr. Stefani' on it."

The 43-year-old singer jokingly claimed that Garth has been "bullying" him a "little bit," and he lamented the fact that there's nothing he can do to get back at him. "It sucks because Garth is kind of off-limits," Blake said with a laugh. "You can't mess with him because he's like the godfather of country music."

Garth, however, denied he ever treated Blake that way, jokingly saying, "You ever think this big of a boy has been bullied, ever?"

That didn't stop Garth from teasing Blake about his stage fright before their performance that night. "Blake's worrying about throwing up. I'm just thinking, 'Be as tall as you can and suck it in!' " the 57-year-old country music star said with a laugh.

Despite their playful banter, Blake has nothing but good words for Garth. In Monday night's (July 22) episode of Garth's Facebook series "Inside Studio G", the "Austin" singer revealed his reaction when he was first asked to team up with Garth.

"It's like, 'What?! This is crazy,' " he recalled. "He's the guy that, literally, between Garth and George Strait and Earl Thomas Conley, there's a handful of artists that had that kind of impact on me. Not just that I was into their music; it was the kind of thing that made me understand what I wanted to do with my life. I wanted to be like those guys. I wanted to be on the radio. When I saw [Garth's] first television special, it was like, 'I wanna be that guy.' "
