Taylor Swift was the suprise musical guest on Jimmy Fallon. This is after Jimmy lost his Mom and his first show back Taylor was asked if she could do the performance and she was totally for it. Jimmy, of course still very upset showed a lot of emotions after the performance of one of her songs from “Reputation”.

Taylor was already in New York to perform on “SNL” so she was all for the support and doing the show.
