Chris Pratt is getting in touch with his country side.
The "Guardians of the Galaxy" star made a surprise appearance at two iconic music venues in Nashville Thursday night and hit the stage to sing some country tunes.
Pratt hit up Robert's Western World in downtown Nashville sometime after 11:30 p.m. and performed a rendition of Johnny Cash's "Folsom Prison Blues." He also stopped in at Tootsie's World Famous Orchid Lounge, where he got on stage with the band to sing some more songs.
At both places, fans took to social media to post their surprise and delight over his impromptu performances.
