Ben Affleck was on dad duty in LA yesterday. He took a matching Violet and Seraphina to the farmers market, where they picked up produce and bought a bouquet of flowers. Perhaps the bright blooms were a surprise for mom Jennifer Garner, who's currently pregnant with the couple's third child. Jennifer Garner's baby bump has been on display during her many outings lately, including a Starbucks stop with Seraphina last week. Jennifer is all about her girls when Ben is busy working on his current project, Argo. It's his latest directorial effort, and it looks like there's more behind-the-camera work in store for the actor. Ben is apparently Warner Bros. pick to direct the big screen adaptation of Stephen King's The Stand.
