Meryl Streep can soon add one more role to her resume: grandmother.
The Oscar winner’s oldest daughter, actress Mamie Gummer, is expecting her first child with fiancé Mehar Sethi, her rep confirmed to Page Six on Saturday.
The pair got engaged in August.
This will be the 69-year-old’s first grandchild.
She has three other children with longtime sculptor-hubby Don Gummer: Henry Wolfe Gummer, 39; Grace Gummer, 32, and Louisa Gummer, 27.
Mamie, 35, starred in the 2015 flick “Ricki and the Flash” with her famous mother, where they took on a different mother-daughter relationship. The film tells the story of a rock-star mom who returns home to patch up her less-than-perfect relationship abandoned grown-up kids.
Gummer was previously married to actor Benjamin Walker, which lasted for two years. Sithi is a producer and writer, and has written for shows including “The Mick” and “Bojack Horseman.”
