Taylor Swift treated an ailing fan to a “surreal and amazing” treat.

Grace Markel, seven, was involved in a terrible car accident on August 10 outside the singer’s Chicago concert venue. The child suffered “two skull fractures, a slight left orbital fracture, multiple head lacerations, a severe concussion, and road rash over her face and body”.

However Taylor made her day on September 21 when she surprised the youngster and her family with an intimate greeting after her Nashville gig.

"Taylor greeted Grace by her name and immediately knelt down and hugged her," the little girl’s mother Amy told People magazine. "She told Grace she had a cold and asked Grace to sing extra loud to help her out.

"Taylor's mother told Grace she was so sorry about what happened to her, and she gave me a hug saying she sympathised with what we'd been through. It was so surreal and amazing."

The 23-year-old country star thanked Grace for wearing one of her official merchandise T-shirts and she autographed the sleeve, writing: "I heart Grace! Taylor".

Following that they hugged before posing for photographs and then Taylor hit the stage.

Grace was nervous about the encounter with Taylor, but the songstress turned out to be "nice and tall and pretty".

"[The meeting] was just a warm and genuine exchange that made it feel like time has stopped, and it was just the two of them," Amy added.

"It's so hard to reconcile what we witnessed at the time of the accident with her amazing recovery," Grace's mother says. "We feel so very lucky and blessed."
