Mamie Gummer is engaged!


Meryl Streep‘s daughter, Mamie Gummer, and her actor boyfriend Ben Walker are now engaged after about a year and a half of dating.

The 26-year old actress announced the news last Monday in New York at the Whitney Museum of American Arts Gala. Walker proposed two days before the gala night and did it the old-fashioned way. “My mom loves him!” she added.

The couple met on their broadway performance “Dangerous Liaisons” in April 2008.
