English singer-songwriter Ed Sheeran made a fan’s day when he took a break from touring to visit her in the hospital in Auckland, New Zealand.

Friends started a social media campaign on Facebook, Twitter and Instagram last week using the hashtag #KiaOraEdPlsVisitJess to help 19-year-old leukemia patient Jess Knight meet the musician. She bought tickets to his concert last year, but could not make it because she was undergoing chemotherapy.

Knight thanked her nearly 4,000 Facebook supporters, calling Sheeran “a lovely guy! Really genuine and down to earth. I couldn’t stop smiling!”
