• Ben Affleckand Jennifer Garner in the lobby of the Ritz-Carlton in Georgetown Thursday afternoon. Both in jeans. He warmed his hands by the fireplace, chatted with guests; she looked very pregnant. He’s in town to film ’70s Iran hostage drama “Argo.”
• Diane Keaton late-lunching at the Newseum food court Thursday. Long black coat, gray brimmed hat, glasses, big-heeled. . . Booties? Shoes? Shooties? Posed for photos with a group of school kids. The actress was in town for a Diane Rehm segment and a lecture at the 6th and I Synagogue promoting her new memoir.
