Tucker Carlson Hangs Out at Kid Rock's Nashville Bar Ahead of Interview

Tucker Carlson has a forthcoming interview with Kid Rock -- and it seems they got pretty chummy off-camera ... hanging out at the latter's bar and having a few laughs.

The FOX News host was spotted letting his hair down Saturday night at KR's Big Ass Honky Tonk restaurant in Nashville, where he was given the VIP treatment right from the get-go.

We're told Tuck was whisked away to the VIP "Cadillac P***y Room," and eventually took in the musical showdown below from an upper deck area ... where he and Kid were chopping it up and enjoying some beverages.

Eyewitnesses even say that Kid got on the mic at one point and announced that Tucker was in the house, to which the audience roared and chanted "USA." There were other types of chanting too, BTW.

Kid eventually helped kick off a "Let's Go Brandon" war cry, which as you know is not-so-hidden code for "F*** Joe Biden" -- something that's become a go-to slogan for conservatives.

If you're wondering what Tucker Carlson was even doing there to begin with -- look no further than this clip he teased over the weekend, which foreshadows an interview he's airing with Kid on Monday ... where they discuss why the rocker isn't "cancelable."

In Kid's eyes, he's not beholden to any corporate interests ... which means he can say and do as he pleases. He also just doesn't "give a f***," which got a chuckle out of TC.
