Macklemore and Ryan Lewis are the kings of making the catchiest, danciest pop songs around. Case in point? Their latest hit, "Dance Off," which you can find us grooving to at any given moment here at DS. So we were super excited when they took their performance on The Tonight Show Starring Jimmy Fallon to the next level with—wait for it—a true dance off, featuring DS favorite, Mishay Petronelli. Check out all the fun below!
