Published Jan 28, 2016Sia's This Is Acting album finally drops tomorrow (January 29) and the pop star stopped by The Tonight Show last night (January 27) to celebrate the occasion.
Wearing her signature black-and-white wig, and joined by a couple of similarly styled dancers, Sia delivered "Cheap Thrills" for the television audience.
Following the solid, albeit fairly standard performance, Sia got together with host Jimmy Fallon, house band the Roots and another of the show's guests, actress Natalie Portman, for something a little more fun.
The group all donned their matching Sia wigs for a rendition of traditional New Orleans song "Iko Iko," putting an artsy twist on the Southern classic.
Watch footage of both performances below.
