For his latest round of Carpool Karaoke on The Late Late Show, James Corden picked up Sia, which is a wonder because Sia could barely make it to the car with her vision-blocking wig. Always one to give it his all, Corden donned a matching wig, but not before belting out "Chandelier" and having an important conversation on aliens. Then Corden informed the world about Sia's impressive egg-carrying hands. There was a lot going on.
