Brad Paisley fans got a nice surprise in Orlando, Fla., when Rascal Flatts joined him onstage during a show on Paisley's Beat This Winter Tour on Jan. 25.

The band joined Paisley for a rendition of Merle Haggard's 'I Think I’ll Just Stay Here and Drink,' as well as for their hit 'Fast Cars and Freedom,' which turned into a singalong with the crowd.

Paisley and Flatts lead singer Gary LaVox joked around between the songs, laughing about the fact that their shared booking agent had "double-booked" them for the night.

"These guys, I feel like we graduated high school together," Paisley said. "We've known each other since we were wee little lads. I don't know what you were doing tonight that you had nothing to do. You're booking agent's not very good, is he?"

"Thank you so much for having us, man," LeVox said to Paisley, setting the jokes aside. "We just wanted to come out and see the show and for you to bring us up here on stage ... it's really cool of you."

The Beat This Winter Tour continues through March, but Paisley already has this summer filled with tour dates. A full tour schedule can be found on his website. He is also set to make his second cameo appearance on the ABC series 'Nashville' on Jan. 29.
