Sia isn't like other pop stars, but if you think her face-obscuring wigs are the reason, just wait until you watch her revealing Carpool Karaoke with "The Late Late Show's" James Corden.

Over the course of their wild ride, the Australian hit maker opens up about out-of-this-world issues and shows off one talent that has absolutely nothing to do with music.

After rousing duet renditions of "Chandelier" and "Elastic Heart," Sia revealed — with a little prompting from Corden — that she believes aliens exist.

"You know, I only believe in them because I watched a video of the ex-Canadian minister of defense just saying plainly he knows for a fact that the American government are working with five different alien races," she explained. "And my blood ran cold, and I was like, 'That guy is the ex-Canadian minister of defense. He's not just some guy on YouTube!' "

As for Corden, he's just fine with the thought of our future alien overlords, as long as "they only want to go on 'The Late Late Show.'"

Corden then made his guest feel a little less alien by adopting her signature look.

But it wasn't all wigs, songs and "X-Files"-like banter. Before the commute was over, Sia shared her knack for a balancing a dozen eggs at once on the back of her hands — which is just one small part of the wacky and worthwhile video that must be seen to be believed.
