Meryl Streep has played every role under the sun — but now she is getting ready to take on a new role in real life.

The mother of 4 will soon be a grandmother of one, as well!

Us Weekly has confirmed that the Oscar winner’s daughter, Mamie Gummer, is pregnant with her first child.

The Good Wife actress was previously married to actor Benjamin Walker for 2 years, but they split up in 2013.

Since August, the 35-year-old has been engaged to BoJack Horseman screenwriter, Mehat Sethi, and has been showing off her growing baby bump — most recently at the premiere of her mom’s new film, Mary Queen of Scots.

The bundle of joy will be the first grandchild for Meryl and her husband, Don Gummer, who are also parents to Henry, Grace, and Louisa.

We’re sure that Meryl will take it on with aplomb!
