Some lucky Steven Tyler fans got to see a once-in-a-lifetime moment at CMA Fest in Nashville. Martina McBride joined the Aerosmith singer onstage for a scorching rendition of the band's classic hit, "Cryin'," which aired nationally on ABC's Country's Night to Rock on Wednesday (Aug. 3).

Tyler took the stage at the annual country music festival and fan convention to promote his debut country album, We're All Somebody From Somewhere. McBride released her latest album, Reckless, recently via Nash Icon, making her Tyler's labelmate under the umbrella of Big Machine Label Group.

"Cryin'" was released as a single from Aeromsith's Get a Grip album in 1993, and scored the legendary classic rockers a No. 1 hit. Tyler performed as part of a regularly scheduled gig at Nashville's Nissan Stadium during CMA Fest, but McBride's guest appearance was an unannounced surprise. The two powerhouse vocalists delivered a scorching dual rendition that you can check out in the video above.

Tyler has already released two country singles, "Love Is Your Name" and "Red, White & You," and he recently released his full album, which he is supporting with a tour.

“I headed down to Nashville last spring to start working on this project, wrote some kick ass songs with some of Music City’s finest songwriters and now we get to share them with the world on July 15,” he tells Ellen DeGeneres. “Country music is the new rock ‘n’ roll. It’s not just about porches, dogs and kicking your boots up. It’s a whole lot more. It’s about being real. And nothing is more real than understanding we’re all just somebody from somewhere.”
