The 39-year-old actress was pictured showing off her post-baby figure in a tiny floral string bikini with neon yellow ties on a beach earlier this month, reported Us magaine.
Later, the actress took off her top completely for a swim with Bardem and their two-year-old son, Leo.
The couple are enjoying downtime before they embark on a press tour to promote their latest project together, "The Counselor", a Ridley Scott-helmed thriller that also stars Brad Pitt, Michael Fassbender and Cameron Diaz.
