SCROLL DOWN FOR VIDEO
Taylor had dropped into the hospital to visit fans and she reportedly asked the young man to play a song for her after he revealed he played the keyboard.
"I decided to play a song I had recently started working on which was Someone Like You, by Adele. She said she would sing what she knew, and I said that I would play as much as I knew", revealed the lucky fan.
"This was the most amazing moment in my life being able to accompany Taylor Swift. She is super nice and cordial and probably made everyone's day here at the hospital.
It was so great of her to come out specially to visit all of us here at the hospital. And in case you are wondering, I did get a hug from her, unfortunately it wasn't caught on video."
The blonde beauty is known for surprising her fans, and regularly invites them backstage at her concerts. In recent days the 24-year-old has been inviting fans around the United States to visit her home and attend secret listening parties for her new album, 1989.
While promoting the new album, which takes Taylor away from her country roots and into a poppier direction, she admitted that she has not dated at all since splitting from her last ex-boyfriend, Harry Styles, in 2012.
Taylor is known for her lyrics which focus on relationships and love, and she added: "I feel like watching my dating life has become a bit of a national pastime.
"And I'm just not comfortable providing that kind of entertainment anymore. I don't like seeing slide shows of guys I've apparently dated."
