Reese Witherspoon’s son Deacon, 17, is growing up so fast! The 45-year-old actress was photographed out and about with Deacon at the Brentwood Country Mart in Los Angeles, California on Tuesday September 7. The Morning Show star’s teenage son looked super grown up, especially as he stood much taller than his mom. The mother-son duo looked like they were having a great time on their bonding shopping trip.
