Madonna and Guy Ritchie – $2.1M

Guy Ritchie put a ring on Madonna’s finger with a $2.1 million ceremony. Madonna bore a son, Rocco John Ritchie in 2000. The power couple didn’t manage to hold their union together, though, and had to pull out the divorce papers in 2008. Nonetheless, they had an unforgettable wedding, with Madonna clad in a Stella McCartney dress (which reportedly cost $800K) strutting in a Scottish castle—which they booked entirely for the lavish occasion. We sure can’t imagine spending that much on a wedding—especially if it ends up in a messy divorce.

Next is another royal wedding. This time, it’s in Sweden!
