The 40-year-old mom of three took to social media on Thursday to show off the gigantic beach ball she bought on a late-night whim, and she's understandably excited. "If ya can't tell, I'm very happy about my late night online purchase!! #GiantBeachBall #VacationFun," she captioned the snap (below) of herself standing next to the biggest beach ball we've ever seen and wearing a euphoric childlike grin. Seriously, can you blame her? Look at that thing! Witherspoon—who recently wrapped filming on her new HBO miniseries, Big Little Lies—has been enjoying some much-needed fun in the sun with her family this week, and she hasn't been shy about sharing a few glimpses of their tropical retreat on social media.
