This last weekend, in between running around surprising fans at theaters showing their movie, the Jonas Brothers made a special stop at Jayla Cooper’s house. Jayla is a terninally ill 9-year-old struggling with leukemia who was only given a few weeks to live by her doctors. Jayla’s last wish was to marry her 7-year-old friend Jose Griggs, another child sick with leukemia, who Jayla met at the hospital.

The two kids chose the Jonas Brothers’ Love Bug as their first dance together at their wedding, and when the Jonas Brothers found out they showed up at Jayla’s house and serenaded her. The video is tear-jerking, so get out your tissues before you watch!
