James Corden has, yet again, successfully proven that singing in the car is absolutely entertaining and legendary—especially when it's done with a celeb.

In the Late Late Show host's latest Carpool Karaoke adventure, he was joined by none other than Sia, who rubbed off some of her signature style on the funny man, himself. If you were hoping to catch a glimpse of Sia's face, you're out of luck. She continued to keep her mug covered with her half-platinum, half-black blunt wig, which hung down passed her nose (good thing she's not the one behind the wheel!).

Corden decided to match with his guest, rocking a similar wig, but one that was safe enough to operate a moving vehicle.

The duo sang some of the biggest songs Sia's performed and written, including "Chandelier," "Diamonds," "Elastic Heart," "Alive" and "Titanium."

Corden even poked fun at the fact that Sia kept her face hidden when he was chatting with Ryan Seacrest during E!'s Live From the Red Carpet at the Grammy Awards Monday night. "It could be anyone," Corden joked. "It's just a chin, really. I hope it's Sia. We're telling everyone it is."

Sia joins a growing list of A-listers who have participated in the popular late-night bit, including AdeleElton JohnOne DirectionJustin Bieber and more.

The Late Late Show With James Corden airs weeknights at 12:37 a.m.
