Carrie Underwood joins James Corden for ‘Carpool Karaoke’

We already knew Carrie Underwood could sing.

But we learned quite a bit more about the “American Idol” winner during her stint on “Carpool Karaoke” with “Late Late Show” host James Corden.

Like the fact that she knows the lyrics to every Wham! song, or that she can hold a note for an inordinate amount of time.

Also: She finds her hockey player husband’s fights a turn on.

Say it ain’t so.

“Do you get worried when he has a fight?” Corden asked the singer.

“Have you seen his latest fight?” Underwood said. “He knocked a guy’s tooth out. It was pretty hot.”

(Here’s the fight, in case you’re curious.)

Underwood sang a few of her classic hits with Corden during their karaoke session, including “Jesus Take the Wheel” and “Before He Cheats.”
