Taylor Swift recently finished up a string of shows in Nashville, Tenn.
At her show last Saturday, the 21-year-old singer surprised her fans with a special guest – Andy Grammer!
Andy came on stage and joined Taylor for a duet of his popular song, “Keep Your Head Up.”
“Thank you Nashville for an unforgettable night. Thank you Tim McGraw, Kenny Chesney, and Andy Grammer for joining me onstage! That was crazy,” she tweeted.
