I may or may not have cried a little at how sweet this was. :3
I guess it's sweet for those who are into that sort of thing. At least she doesn't feel humiliated by all the attention.The lady wouldn't be embarrassed. She and her fiance are singers/dancers/actors and she's also a choreographer. Someone described who the couple are in the comments on the video's page.
I'm not crying, I've just been cutting onions.
