Meryl Streep starred in “Sophie’s Choice” but it was her daughter Mamie Gummer who had to choose Monday between her mom and her husband, Benjamin Walker. Streep performed in a reading of “Romeo and Juliet” with Kevin Kline for the Public Theater’s Shakespeare in the Park 50th anniversary gala, while Walker walked the red carpet at a premiere for his action extravaganza “Abraham Lincoln: Vampire Hunter.” “It was poor planning on somebody’s part,” Gummer lamented Tuesday, telling us she went with Walker. “It was really inconvenient for me.” Gummer also recalled that her hubby “broke a couple of lamps around the apartment” while he practiced killing vampires with an ax for the film.
