Carrie Underwood joined James Corden on "The Late Late Show" on Wednesday night, which can only mean one thing: another edition of Carpool Karaoke!

The country singer was just the latest guest on what's become a signature sketch for the show: Corden invites his guest into the passenger seat of his car, drives around with them, and they sing their little hearts out. And on Wednesday, Underwood obliged — not only by duetting with him on her own tunes, but the pair also took a trip into 1980s nostalgia and into a cowboy outfit shop!

After a rendition of "Smoke Break," Corden queried Underwood about her husband, hockey player Mike Fisher and wondered if she ever worried when he got into fights during a match.

"Have you seen his latest fight? He knocked a guy's tooth out!" said Underwood, leaving Corden horrified.

And when the pair finished up "Jesus Take the Wheel," a miracle happened: Corden took his hands off the steering wheel and the car continued on. "It's happened!" he cried out.

But the best moments came later on, when Corden decided he wanted to become a country music superstar, and so needed the right outfit. "Boots are our roots," admitted Underwood, who helped him into a pair of $800 cowboy boots, a $200 hat and $2000 leather vest.

Again, Corden was horrified, but this time at the price. "That's nothing," said Underwood.

"I'm sorry, we're not all multiplatinum recording artists," Corden shot back.

"It's an investment!" she protested.

Can't argue with that. Or with the fact that Underwood happily admitted that she knew every Wham! lyric ever written, then proved it. Exit with the pair back in the car, driving away and bopping to "Wake Me Up Before You Go-Go."

As it should be! Check out the video for more boot-scootin' fun.
