Ashton Kutcher and Mila Kunis’ Post-Wedding Plans… Road Trip!

It’s not quite a honeymoon, but Ashton Kutcher and Mila Kunis took their own vacay after their turn at the altar for her brother’s wedding last weekend.

Forget the tropics or Europe– these Hollywood heavy-hitters decided to put on their tourist hats and hit up America’s most historic landmarks.

First stop: Chattanooga, Tenn.

The celeb couple drove through one of the city’s most popular attractions, Rock City, Monday to the surprise of their tour guide.

“When I got to work I was told Ashton Kutcher and Mila Kunis were going to be on my tour,” Micah Jones told Celebuzz.

“I thought, that’s cool. It’s going to be an interesting tour.”

That it was. The Two and a Half Men funny guy, who told Jones he and his lady love were on a road trip, showed off his trademark silly sense of humor as he and another family of four toured the cool caves filled with stunning rock formations.

“They were at the back the whole time, but were totally interested and asked a bunch of questions about the caves,” Jones said. “Part of the tour is me making terrible rock-related puns and they had fun contributing. They were really funny the whole time. Even the family got into it!”

“I can’t remember exactly what they said, but I wish I did so I could use it.”

When the tour came to an end after an hour and a half, the pair, who’s been dating over a year, took home memories with pics in front of Ruby Falls, said Jones, who acted as their photog, and selfies at Lover’s Leap (aww!). And although they turned down photos with fans, they were happy to sign a few autographs.

And their next stop?… Nashville, apparently, per Rock City employees.

Even Kutcher commemorated their southern pit stop with a shout-out to cavern gnome artist extraordinaire, Matthew Dutton, via Twitter:
