Seraphina Affleck got a chance to hop on a pony during an LA farmers market outing with mom Jennifer Garner and sister Violet. Jennifer took the kids to their local market after the family, including Samuel, visited a hardware store in Pacific Palisades on Saturday to pick up gardening supplies. She has had a busy weekend with her kids, kicking off with a Friday karate class excursion with Violet and Seraphina. Her family time comes just as news has surfaced that Jennifer Garner may costar with Kevin Costner in a new football film. The new job opportunity would be Jen's second for this year as she wrapped up filming Dallas Buyers Club with Matthew McConaughey and Jared Leto in January.
