While it's no carpool karaoke session (yet), James Corden gave a little sneak peek of how he and Taylor Swift would vibe when he filled in for one of her backup dancers at The Forum before Jingle Ball. He was his most James Corden self; she was typical witty, sarcastic old Taylor Swift.
The combo was awkward but wonderful, at the 10:20 mark. (Swift got a particularly savage burn in there):
Corden 'filled in' for the Forum's general manager in the 14-minute video sketch. He gave fellow Jingle Ball performers Niall Horan a massage, Demi Lovato a pep talk, Liam Payne a cuddle buddy, Ed Sheeran extra security, and Sam Smith a therapy session. It's a lot in the best way.
