Kiefer Sutherland and Robert Downey Jr.

Downey “kind of” lived with both longtime girlfriend Sarah Jessica Parker and Sutherland for three years around the time the men co-starred in the 1988 movie 1969.

The Iron Man star told Howard Stern in May 2016, “He was a shoulder [for her to cry on]. Better him than some stranger.” (Photo: Getty Images)
