Earlier in the week, Jennifer was spotted attending an open house while chatting on the phone in Beverly Hills.

“We knew we needed somebody who was charming and could be seductive, who could be a ladies’ man, a guy’s guy, a frat boy,” director David Fincher recently shared to EW about Jennifer‘s husband Ben Affleck in his highly anticipated film Gone Girl. “But most important, [someone] who had the wits and experience of knowing that situation. The gift of having Ben Affleck is that this is a guy who knows. He knows what a lose-lose situation is and understands what’s funny about it, however sad.”
