James Corden sings Carpool Karaoke with Sia on 'Late Late Show'

One of the more anticipated Carpool Karaoke guests on James Corden’s Late Show was “Chandelier” singer, Sia, with fans wondereing if she would show her face. She appeared on his Feb. 16 show and kept her signature look, covering up with her blonde hair and a big bow.

Like the many guests before her, Sia sang along to her biggest hits with Corden, like “Alive,” “Diamonds," "Elastic Heart” and "Titanium.”

She said of always covering her face that the main reason is for “privacy,” adding, "I don't wear this unless there's cameras around. I only wear this just to try and maintain a modicum of privacy."

Sia went on to say when she began to get famous, it was “destabilizing” her as a former addict, so she wanted to keep some anonymity to help her feel more grounded.
