Jennifer Garner and her middle child, Seraphina Affleck, stopped to get coffees at Caffe Luxxe in LA yesterday. Jen's holding down the fort on the West Coast with Seraphina and her siblings, Samuel and Violet, while dad Ben Affleck does a final press push for his third directorial effort, Argo, in NYC. Last night, Ben hosted a special screening of the CIA thriller, which is out Friday, for famous friends like Matt Damon in the Big Apple. Ben's also been making the interview rounds, stopping by GMA, Live! With Kelly and Michael, and even more shows. In one of his latest interviews to air, Ben Affleck's baby son, Samuel, was the topic of discussion. Ben spoke about his dreams for the little one, joking that Samuel's already sleeping with a baseball glove to enhance his chances of being a success on the diamond.
