Meryl Streep's little girl is getting married!
Actress Mamie Gummer confirmed to Usmagazine.com that she and actor boyfriend Ben Walker are engaged.
"He proposed two days ago," the actress, 26, announced Monday in New York at the Whitney Museum of American Arts Gala, noting that he "surprised" her with a custom-made ring. "He did it on one knee!" she said.
Dating for about a year and a half, Gummer and Walker met working on a short film, and later performed together in a spring 2008 Broadway production of Les Liasions Dangereuses.
"My mom loves him!" the Taking Woodstock actress gushed. Gummer is the second eldest child to Oscar-winner Streep, 60, and sculptor husband Don Gummer, who have four children.
"We are very happy!" Gummer said of Walker, her date at Monday's gala.
