Meryl Streep and Don Gummer – 42 years

Meryl Streep has long had a reputation as one of the greatest actresses in the history of film. But even greater than her acting may be her marriage to sculptor Don Gummer, who she’s spent the past 40 years with. Meryl and Don have kept their marriage out of the spotlight for the most part, which seems to be a common theme with many successful celebrity couples.

Over the last 40 years, the couple has had four children together. Not too much is known about Meryl Streep and Don Gummer’s marriage, but the two seem to be as happy as ever. We can only guess that keeping private matters private has something to do with that.
