This has nothing to do with their characters on the show, and it just goes to prove that they have so much more to offer beyond those two (admittedly quite iconic) characters. Not that we didn't know that already — both are accomplished women who repeatedly prove themselves to be awesome in interviews and on red carpets, time after time. This medley of seasonal classics is so catchy, it oughta be illegal, and their voices sound just gorgeous. Also, we're loving that awkward sweater man in the background. Nice touch.
