5. Kim Kardashian and Kris Humphries

Kim Kardashian and NBA star Kris Humphries began dating at the end of 2010. A short five months later, Kris popped the question with a 20-carat ring and "Will you marry me?" spelled out in rose petals. The two (and plenty of hired help) then began planning the most epic celebrity wedding of the year. Their big day was August 20, 2011 and then 72 days later they called it quits.
