This seems like a natural alliance...
Jelly Roll teamed up with Dunkin' for National Donut Day. He did an ad where he talks about his nickname, and how he got it because he loves donuts so much.
He also shows off a few donut-dunking styles. But maybe skip the second one and don't SMASH it down onto your scalding-hot cup of coffee.
They also announced some new merch, including a pink hoodie with the word "JELLY" on the front.
