Gronkowski, Ortiz go country in their latest iced coffee music video

Rob Gronkowski and David Ortiz have been this summer's hottest new artists with their funny music videos about Dunkin Donuts' iced coffee.  

In their latest summer jingle, Gronk and Papi go country to switch up their style. They trade in their jerseys for a flannel and blazer, topped off with cowboy hats, of course.

Check out their newest music video below:

Needless to say, both Big Papi and Gronk could use a singing lesson or two ... or twelve. Aside from being off-tune and off-beat, it's great. Especially with the dancing iced coffee in the background.

What these guys will whip up next, no one knows.
