Ben Affleck and Jennifer Garner spent the afternoon side by side in Brentwood today. They showed sweet PDA during the lunch date as Ben put his arm around his pregnant wife and the couple shared a laugh. Jennifer's just one of many Hollywood moms-to-be including Beyoncé Knowles, Keri Russell, and Bryce Dallas Howard. Ben and Jennifer were also out together yesterday, when they grabbed breakfast with their youngest daughter, Seraphina. Ben's busy schedule filming Argo seems to have lightened up a bit, but he's still sporting long hair and a scruffy beard for his big-screen character. His working streak will continue even when he wraps his latest project since Ben already has a new movie in the works with pal Matt Damon.
