Big Papi & Gronk Sing in New Dunkin’ Donuts Ad [VIDEO]

As if it wasn't enough that our friends at Dunkin' gave out free donuts last Friday...now this!

Boston Red Sox designated hitter, David Ortiz and New England Patriots tight end, Rob Gronkowski are hangin' poolside with what will be this year's summah hummah. The song is called Sippin'. It's for a new Dunkin Donuts commercial and features an auto-tuned Big Papi and Gronk havin' some warm weather fun that includes them riding a tandem bike. Probably my favorite moment is when Ortiz does his cup solo!
