21. Meryl Streep & Don Gummer

This couple is usually seen in red carpet events and award shows, where Meryl Streep is a mainstay. According to Elle, the couple tied the knot in 1978, but detailed information about their relationship is scarce. Well, if you’d search up the lovebirds, only photos of them in formal attire are available. Though Streep is a world-renowned actress, she does love living a private life. In fact, she owns a $3.6 million home in Pasadena, California, which is not big but offers privacy, according to Home Stratosphere. It wasn’t mentioned but it won’t be surprising if this 3,087-square-foot house has the best home security system.

Aside from the year they got married, other known information about their relationship is that they wedded six months after Streep’s husband John Cazale passed away and that she and Gummer have four children, Henry, Mary Willa, Grace, and Louisa, all of whom work in the entertainment industry.
