Pregnant Jennifer Garner kept her girls busy over the weekend, starting with a Saturday trip to the nail salon and a visit to a friend's birthday party yesterday. Jen's kept up a packed schedule in recent weeks and doesn't seem to be slowing down. She's been spotted all over town running errands with Seraphina and dropping Violet off at her various activities. When it came to picking up a gift for yesterday's bash, though, Jen left the shopping duties to Ben and Seraphina. Ben and Sera stopped by the Brentwood Country Mart prior to the celebration, and she even left with a heart shaped lollipop of her own. The Garner-Affleck family doesn't hide their affection, which is one of the reasons Jen and Ben are among our favorite celebrity couples on Valentine's Day.
