Sia And James Corden Get Wigged Out For “Carpool Karaoke”

James Corden never seems to be able to get to work on time or without a celeb. This time James got help from a wigged-out  Sia who he found on the street. The singer/songwriter belted out most of her hits including,  “Chandelier,” “Elastic Heart,” “Alive” and Rihanna’s “Diamonds,” which Sia wrote. In between belting out some hits Sia and James talked about Sia’s wigs, aliens and being double jointed in her hands.
