Now that’s one way to beat the summer heat! Liev Schreiber and his 2-year-old son Alexander ‘Sasha’ Pete enjoy a good soak at Washington Square Park on a steamy Monday in the Big Apple.

Notice the new artwork on Liev’s forearm? The actor has had “Kai” inked on his left arm, and “Sasha” on the right!

Also with the pair? Mom Naomi Watts and baby brother Samuel Kai, 8 months (not pictured), who stayed out of the spray!
