Couple Nickname: None
Dated Between: 2000 - 2003

There isn't enough space on the Internet to list off all the reasons why Angelina Jolie's marriage to Billy Bob Thornton was creepy as hell, so we'll just go with a few to start you off: The couple wore vials of each other's blood around their necks; they would appear on red carpet interviews in a post-coital haze and admit to having just had sex in Thornton's truck; they admitted to using knives during sex; and they reportedly built a "sex dungeon" in their home.

And this all started after Billy Bob Thornton abruptly left his then-girlfriend Laura Dern, who is quoted saying of the affair, "I left our home to go and make a movie and while I was away, my boyfriend got married and I never heard from him again."
