This is the most adorable video..
Hayden helped to save Skye's life by being her bone marrow donor, and then invited the sweet 3-year-old to her wedding!
The bride-to-be became a donor while she was in college, and was soon matched to a little girl who had a rare and aggressive cancer.
After the surgeries, Hayden just fell in love with Skye, and the hope is everyone, especially Skye, will live happily ever after!
