4. George Clooney And Amal Alamuddin
While most marriage ceremonies last a day, George Clooney and Amal Alamuddin made it a weekend affair. Along with guests Matt Damon, Bono, and Emily Blunt, they held a trio of ceremonies in Venice, Italy. The entire ordeal, which included water taxis and cocktail parties, cost them around $4.5 million.
5. Prince Charles And Diana Spencer
One of the biggest wedding ceremonies of all time easily belonged to Prince Charles and Diana Spencer. The whole shebang was viewed live on TV by over 750 million viewers worldwide. It might’ve cost $110 million, but the royal family obviously had no problem taking care of the bill.
