Watch Natalie Portman and Jimmy Fallon Sing with Sia–While Wearing Sia Wigs


Well, this is pretty great! Sia appeared on The Tonight Show with Jimmy Fallon on Wednesday night and performed "Iko Iko," a song she's covered previously. She was joined by Natalie Portman and The Roots and the best part is everyone wore a Sia wig for the number. The performance is the definition of joy, really. Sia also performed "Cheap Thrills" (from her new  album This Is Acting)  and while the video of that isn't available just yet, please do enjoy these photos:
