Taylor Swift warmed the hearts of countless fans when she made a surprise visit to Hasbro Children's Hospital in Rhode Island yesterday, March 31. The kindhearted singer -- who recently spent five hours greeting cancer patients at the Sloan-Kettering hospital in New York -- spent hours talking and posing for pictures with patients, even treating them to a short performance.

Swift, who recently purchased a house in the state, brought her dad along with her for the visit.

"A huge THANK YOU to the amazingly sweet and talented Taylor Swift who visited Hasbro Children's Hospital today!" the hospital wrote on their Facebook page. "Taylor spent lots of time visiting with our young inpatients at the hospital today, and even played a song for the kids on our 6th floor med/psych unit. It was such a special day for a lot of our kids, and we are so thankful to Taylor and her dad for choosing to spend their time with us and put smiles on so many faces!"

And put smiles on faces she did -- as evidenced by the dozens of fan photos that poured in all across social media. Check them out below.

Taylor even performed 'Mean' at the bedside of one patient. See her sweet performance below:
