As it turns out, Streep is Ronson's mother-in-law.

Ronson married Streep's 37-year-old daughter Grace Gummer in August 2021. Last year, he posted a sweet tribute to his wife on their one-year wedding anniversary.

"When people used to tell me their spouse was their best friend, I thought they were spouting Hallmark nonsense or that they were some freak anomaly of love. So now I guess I'm either someone who spouts Hallmark nonsense or I'm a freak anomaly of love," the record producer wrote on Instagram.

The pair welcomed a baby girl in December 2022.
