Sia Explains the Disguises (again) and Belts out "Diamonds" During Late Show Carpool

Late Show carpool time has rolled around again! This time being solicited by James Corden is Aussie singer-songwriter, Sia.

To those who thought the Diva had been using all those wacky disguises to mask lipped notes, be prepared to eat some pie of the humble variety. Sia kills it on the vocal front. James, on the other hand, unfortunately hinders more than he helps, getting in the way of some of the Diva's ad-libs.

Get into some raw Sia. Freaky, backward hands and all.

Thoughts?
