4. Britney Spears and Jason Alexander (January 3, 2004 – January 5, 2004)
Lesson: Never marry a woman who will shave her head and attack a fan filled with paparazzi with an umbrella.
These two were childhood friends, and just before — or did this spark? — the Great Britney Spears Breakdown of 2007, she spontaneously decided to elope in Las Vegas with Alexander. This was pre-Kevin Federline, mind you. Which means that she was making terrible decisions before the K-Fed incident occurred. Still, once she came to her senses or the booze or drugs wore off, the two realized that it was a mistake and had the marriage annulled shortly thereafter. How romantic.
