Jennifer Garner enjoyed an afternoon with her 9-year-old son Samuel Affleck. The 13 Going On 30 actress sweetly held her youngest child’s hand as they stopped by a Farmer’s Market in the Brentwood neighborhood of Los Angeles on Sunday, Oct. 10. Samuel could be seen holding onto a cream and navy blue colored tote bag for the excursion, perhaps to load up on some fresh baked goodies and other items from the outdoor market.
