What's the wedding show that teaches wedding dance surprises?

Question

I can't figure out what show I'm talking about. It's about a wedding party that usually learns a surprise dance for the reception. They usually change in to a costume or whatnot. They're taught by a professional choreographer. HELP ME!!!
