It's Ali's wedding day, so her father has prepared something extra special for her. A few years back, Ali was in a tragic accident and had to have her jaw wired shut while she was in the hospital.

Now, her Dad has learned so he can sign her a song at her wedding in this emotional clip. This video's giving us all the feels.
