Meryl Streep has become a grandmother for the first time after her actress daughter Mamie Gummer welcomed a baby boy.
The child, whose name and birth date have yet to be revealed, is Mamie’s first with her fiance, Sethi Mehar, who she became engaged to in August (18).
The private couple confirmed the True Detective star’s pregnancy in December (18), reports Us Weekly.
When the new parents tie the knot, it will mark Mamie’s second marriage. She was previously wed to In the Heart of the Sea actor Benjamin Walker from 2011 to 2013.
Walker went on to remarry, making British actress Kaya Scodelario his wife, and they had a baby in late 2016.
Mamie, who co-starred with her superstar mum in 2015 movie Ricki and The Flash, is Meryl’s second kid with husband Don Gummer.
The Mamma Mia! icon and Don, who are based in Connecticut, are also parents to songwriter Henry Wolfe, 39, actress Grace, 32, and model Louisa, 27.
Although Mamie has yet to publicly comment on her baby news, she previously shed a little light on her own upbringing, growing up with such a famous mum.
“Her priority was being our mother, not being a celebrity, and it certainly wasn’t like we had Warren Beatty to the house every Thursday!” she once laughed to the Daily Mail. “I think one of the smartest things my parents did for us was to move to the country when we were small, so we weren’t completely consumed by New York or Los Angeles.
“We did live in L.A. for a while, but my parents didn’t like it – the film industry’s influence can be overpowering, and mum wanted us to know that being famous isn’t the most important thing in life. We had a very normal family life.”
