The 20 Weirdest Celebrity Couples Ever

4. Robert Downey Jr. and Sarah Jessica Parker

Before Robert got his act together and before he was Ironman, he was in a long-term relationship with Sarah Jessica Parker. They were together from 1984 until 1991, and it was only through Sarah’s own patience that they lasted that long. During that time, Robert had a drinking problem and perhaps other problems, and that was something that Sarah would not tolerate. Even Robert later admitted that he was not a good boyfriend to Sarah.
