Kip Moore might have thought he'd beaten Dierks Bentley in a prank war, but he'd better think again.

The pranks began in early January, when Bentley forced Moore to jump into an ice-cold lake to announce Bentley’s upcoming tour, for which Moore will serve as one of the support acts. Moore upped the ante later that month when he trashed Dierks' beloved truck, Big White, by getting his accomplices to pour packing peanuts into the cab, draw a Riser logo on the hood and scrawl graffiti on the sides and back, as well as putting a billy goat in the back, where it promptly made a mess.

Moore probably thought that was the end of it, but his revenge had unintended consequences.

"The prank they pulled, they put plastic over my truck, and then they spray-painted over the plastic. Well, when they pulled the plastic off, the spray paint had reacted with the glue and it left the words," Bentley tells "I’ve been driving around with the word ‘Payback’ on the side of my truck for a month and a half. It’s like he’s still pranking me for a month and a half straight, because this stuff does not come off my truck. One side says ‘I’m to Blame,’ his current single, and the other side says ‘Payback,’ for when I made him jump in the lake. So there will be some payback."

Once Moore realized his prank left a lasting mark, he was horrified.

"[Kip] has been calling me, ‘Man, am I kicked off this tour? I feel so bad …,’" Bentley reveals. "I’ve got a guy who’s going to try to get it off. I might have to get my truck repainted, which would be a big drag, because I’ve had that truck forever. [But] it’s all good. I got three kids. I don’t sweat the small stuff. I love Kip, man. He’s a great dude. [But] it could be a long summer for Kip. And he knows it now, too.”

Bentley's 40-city Sounds of Summer tour kicks off June 5 in Raleigh, N.C. with Maddie +Tae and Canaan Smith on the bill.
