Last month when leukaemia patient Ben went into hospital for a bone marrow transplant he received a rather lovely surprise, he got to perform a duet with Taylor Swift.
Speaking to BuzzFeed News, Ben said Swift traveled from Rhode Island to meet patients at the hospital as a surprise organised by staff.
Ben said Swift asked him to play something for her on the piano in his room
Ben told BuzzFeed there had been no complications since his transplant and he had managed to stay well.
He said he was lucky he had a sibling donor in his younger brother meaning he had a 100% match.
He is asking for people to sign up to BeTheMatch.org so more people in his situation have the chance of receiving a perfect match.
