Some people decide to go the traditional route when planning their wedding, while others opt for something less conventional. Celebrities have a lot of money, so usually, they decide to do something to stand out among others. Sometimes they want only the best, most gorgeous and most expensive dress. Sometimes they go out of their way to ensure security at the ceremony. And sometimes they even take animals to their wedding because it signifies something special for them.

A lot of the things celebrity brides (and grooms) want at their weddings are realistic but cost a lot of money. But at times, they go over the top. For example, $100k for flower decorations? Or $2.5 million to fly all the guests to India? Wedding planners of these celebs certainly thought they went crazy!
