Seriously? OMG! WTF?

Tonight on The Tonight Show, Jimmy Fallon and The Roots invited The Voice coaches to do a mashup of their hits acapella style. The started with Adam Levine, followed up with Jennifer Hudson, somehow got Blake Shelton to blend in before saving, Kelly Clarkson, the best for last.

Oddly enough, not only do they mesh well together as coaches on the NBC show. They also mesh well when they sing as one. Who knew?
