and her 20-month-old son, Benjamin Rein, enjoyed a day at the beach Monday while on vacation in Costa Rica, with dad Tom Brady
back home practicing with the New England Patriots for the upcoming NFL season.

splashed in the waves before spending the rest of the day relaxing on the sand. A day at the beach is a favorite pastime
