Mamie Gummer and husband Benjamin Walker are ending their marriage.
The actress, who starred on The CW's short-lived Emily Owens, M.D. and is the daughter of Meryl Streep, married the Abraham Lincoln: Vampire Hunter star in July 2011. Their reps confirmed the split to Us Weekly, which first reported the news.
"It's very amicable," Gummer's rep says.
Gummer, 29, and Walker, 30, first met in 2008 while performing in the Broadway production of Les Liaisons Dangereuses. They married at her family's estate in Connecticut three years later.
Gummer is one of four children Streep bore with her sculptor husband, Don Gummer. She most recently appeared on the big screen in Steven Soderbergh's Side Effects and was cast opposite Rainn Wilson in the CBS pilot Backstrom.
Walker is starring opposite Scarlett Johansson in the Broadway revival of Cat on a Hot Tin Roof.
