The Jonas Brothers took time out of their surprise theater invasion this past Sunday (March 1) to bring a bit of joy and “Love Bug” to one very special fan, Jayla Cooper, in Grapevine, Texas.

Nick, Kevin and Joe surprised 9-year-old Jayla, who is battling an aggressive form of leukemia.

Jayla gasped and then later received a hug from her favorite musicians after they sang an a capella version of her fave song, “Love Bug.”
