Rock City employees aren't just seeing lights this year, they're seeing stars.
Ashton Kutcher and girlfriend Mila Kunis showed up at Ruby Falls and Rock City to everyone's surprise.
Rock City's President Susan Harris says she wanted to make sure the That 70s Show couple had a normal and fun experience.
"They were actually taking pictures with their camera, they were the only two folks out at lovers leap. So I just walked up and introduced myself and offered to take pictures for them so Ashton gave me his camera, his phone, so I took a couple of pictures for them and then just shook their hands thanked them for coming to visit us and let them enjoy the second half of the trail," said Harris.
Kutcher even tweeted shortly after their visit, "Props to Mathew Dutton for keeping Rock City magical for future generations."
Chattanooga Visitors Bureau Marketing Vice President Dave Santucci says being acknowledged by a celebrity like Kutcher speaks volumes.
"He's got 15 million followers. He's the Godfather of Twitter. You couldn't ask for a bigger celebrity with a bigger following to come through and we're just excited they gave a shout out to Chattanooga, to Rock city.
