The actor, 49, posted a sweet message on Sunday for a fan who has been living with Stage 4 breast cancer for the past six years. The recipient also happens to be a fan of Garth Brooks, so Johnson decided to go country in hopes of making her smile. "I'm so excited right now to deliver this very special message. I'm so excited my cheeks are red," he said in the Instagram clip. "This goes out to a very special woman. A very strong woman. Melissa, A.K.A Missy! "I also know you're Garth Brooks' biggest fan," he later added. "You know I love my country music. So in the spirit of Garth, this one's for you." "I apologize about my singing in keys that don't exist and sounding like I'm experiencing puberty again ???????????????," he wrote alongside the video. "I hope this makes you smile, Missy!" Johnson is constantly finding ways to put smiles on people's faces, no matter the circumstance. ?Batwoman?
