Last night, bar patrons who showed up for a Tom Petty cover band were surprised by an impromptu performance by Carrie Underwood, who decided to join the band on stage!!
The country singer, 39, interrupted her girls night out to jump on stage with Tom Petty cover band The Heartshakers at Fox & Locke bar and venue in Nashville, where they performed the musician's 1981 duet with Stevie Nicks, "Stop Draggin' My Heart Around."
