New country girl duo Miss Willie Brown fired the first shot in prank wars on the new Dierks Bentley tour. Seems the ladies, Kasey Buckley and Amanda Watkins, gave Dierks' Jeep a little makeover.

So Dierks fired back by stuffing 480 beers in “every spot, zipper, and . . . toilet on [Miss Willie Brown's] bus,” as Dierks describes on Twitter. Dierks included a pic of the bathroom, which shows a toilet stuffed with beer and a beer in with the toilet paper.

Even Dierks wonders whether this is really a punitive prank. “Prank or gift?” he tweeted.

Funny thing is, before the beer-stuffing “payback,” Miss Willie Brown asked tourmate Josh Thompson to align with them.

“I told them ‘Hell, no!’ They are on their own for this one,” Josh said.

Bet he might be rethinking that one. Josh could've had a lot of free beer on the table.
