Reese Witherspoon took to Instagram last night to share the most adorable video of her and her youngest son Tennessee, and we are officially obsessed with the sweet little boy. In the clip, the 3-year-old holds his arms around Witherspoon's neck as he looks at the phone and says "Ooh, mama!" The actress—who wears a chic sun hat, striped ensemble, and several necklaces—laughs as she records the sweet mother-son moment. "My #SundayFunday with the little guy ❤️ Hope yours was just as sweet ✨" she wrote alongside the 'gram. The 40-year-old also shared several other photos from her weekend fun earlier in the day, including a picture of Tennessee preparing to eat a delicious BBQ meal and a snap of the star and her too cute French bulldog Pepper. But this isn't the first adorable photo Witherspoon has posted of Tennessee. Last month, she shared several images of the toddler enjoying some Fourth of July fun, including a selfie of the pair in their patriotic red, white, and blue gear.
