Sarah Jessica Parker & Robert Downey Jr
This one may catch you by surprise since Sarah Jessica Parker is well known for her long marriage to Matthew Broderick. But Robert Downey Jr. was actually Parker’s first highly publicized relationship.
While the two never married, they were together for a while. The talented actors dated from 1984-1991. They actually met on the set of a film they were both in, Firstborn. Downey’s issues with substance abuse ended up ruining the relationship.
