Reese Witherspoon Wishes Her "Sweet Boy" a Happy Birthday on Instagram

On Saturday, Reese Witherspoon wished her little boy Tennessee Toth a happy birthday on Instagram. To celebrate the day, Reese shared two snaps: one of Tennessee looking like a stud in blue sunglasses and shorts and one showing off his cool cake. "Happy Birthday Sweet boy! 3 is a magic number," Reese wrote. This isn't the only birthday Reese celebrated recently — Ava Phillippe turned 16 earlier this month, and Reese also honored the occasion with a special shout-out. The wishes are a small slice of Reese's family life, which she freely shares in plenty of frame-worthy pictures on social media. Keep reading to see her birthday posts, and then watch the delightful Dubsmash video of her and Tennessee lip-syncing to "Bananaphone."
