I've seen a few versions of Beyonce's Single Ladies in my time. This gets a special nod because of the number of people, folksy venue, and distracting lack of pants. Oh and there's a really cute proposal at the end.
A video of former Disney Channel darling and recent rehab graduate Demi Lovato catching a bouquet at a friend's wedding has been all over the internet lately. Normally I would think this incredibly boring, but the fact that she beats out the girl to her left who has a good three inches on her is actually pretty impressive.
