As usual, James is aimlessly driving around the streets of Los Angeles, en route to the Late Late Show offices, and - this time, she just happens to stumble up Sia standing roadside with her arms outstretched because she's "really good at directions".

Naturally, as has become customary, James asks her to carpool to work as they just so happen to sing some of the biggest songs she's performed and written, including "Chandelier" and "Diamonds." You may be relieved to hear that James does don a Sia wig, but it's not the full Siam, because he'd crash the car otherwise.
