Dennis Hopper
Dennis Hopper was known for being unpredictable, intense, and deeply tied to the wild side of 1970s Hollywood. So maybe it is not shocking that one of his marriages became legendary for how quickly it fell apart. He married Michelle Phillips of The Mamas & the Papas on Halloween 1970.

The marriage barely had time to become real before it was over. Phillips filed for divorce just eight days later, making it one of those celebrity unions people still bring up because of how fast it collapsed. Even by Hollywood standards, eight days was an impressively chaotic love story.
