Mamie Gummer, star of the recently canceled TV show Off the Map and eldest daughter of Meryl Streep, has married, reports People. The actress married actor Ben Walker (Kinsey, Flags of Our Fathers) last weekend at the family’s Connecticut estate. Among the 150 guests in attendance were Claire Danes, Tracey Ullman, and Laura Linney. The couple, who announced the engagement in October 2009, met while performing side by side in Broadway’s 2008 production of Dangerous Liaisons.
