After driving Justin Bieber around the day of the Grammy Awards, "The Late Late Show" host James Corden picked up Sia for a musical ride around Los Angeles. Corden and Sia belted out tons of the singer's hit songs, including "Chandelier," "Elastic Heart," "Alive" and "Titanium."

The video started off with Corden picking the singer up from the side of the road in one of her trademark face-obscuring wigs. The conversation then turned serious as Sia explained to the host why she wore wigs that covered her face, to "maintain a modicum of privacy."

"I was a singer, already, for 10 or 11 years to mediocre success, and I was an alcoholic and a drug addict," Sia told Corden. "I sobered up, and I decided I didn't want to be an artist anymore, because I was starting to get a little bit famous and it was destabilizing in some ways. So, I thought, 'What doesn't exist in pop music at the moment?' and it was mystery. I was like, there's pictures on Instagram of everyone at the dentist."

Later on in the car ride, Corden put on the same white and black wig that the singer wore, but since he was driving, it did not block his eyes. The singer then showed off one of her hidden talents during the "Carpool Karaoke" video- balancing a dozen eggs on top of two of her hands.
