Taylor Swift's 15 Hour Meet-and-Greet

Taylor Swift spent a lot of time with her fans this weekend -- during a 15 hour autograph signing session in Nashville!

Though Swifty had initially planned to sign for 13 hours at the CMA Music Festival, she went another two -- and by the end of it, hugged 2,000 of the 10,000 fans in attendance.

Taylor's no record breaker though -- Garth Brooks once signed autographs there for an entire day.
