Taylor Swift may be dealing with a case of writer's cramp, after spending almost 15 hours signing autographs for her devoted fans Sunday during the CMA Music Fest. The country superstar, who had originally planned a 13-hour meet-and-greet, started mingling with fans at 8:00 AM and stayed until almost 11:00 PM, thanks to the long list of admirers who spent most of the day waiting in line to meet their favorite singer.

"I'm hearing so many amazing stories from people," Taylor gushed to Nashville's Tennessean newspaper. "And I'm seeing a lot of tattoos -- not like biker tattoos, but girls with little ankle tattoos that say 'Fearless.'"

Greeting more than 2000 fans, Taylor smiled, posed and hugged each person, breaking only to perform a short acoustic set. Fans were also kept entertained with displays of costumes and other memorabilia from the singer's sold-out Fearless world tour.

Back in the studio working on her follow-up to her CMA Award-winning 'Fearless' CD, Taylor will next appear in Music City at the Nashville Rising concert on June 22. Hosted by Tim McGraw and Faith Hill, Taylor will appear alongside some of music's hottest stars, including Jason Aldean, Martina McBride, Carrie Underwood, Miley Cyrus and several others who are donating their time to raise money for the recovery efforts following last month's devastating floods.
