Meryl Streep and her daughter Mamie Gummer stepped out of their Vancouver hotel together yesterday. The duo spent time up north just as news of Mamie's split from her husband, Ben Walker, was announced. Mamie and Ben were married in the Summer of 2011 after meeting in 2008 while working on the Broadway play Dangerous Liaisons. Ben was recently back on stage in Cat on a Hot Tin Roof while Mamie has been focused on the small screen. Her show Emily Owens, M.D. was canceled after just one season, but she's already signed on for the CBS pilot Backstrom opposite Rainn Wilson.
