Naomi Watts and Liev Schreiber didn't let rain get in the way of their workout yesterday. The couple went for a jog in Sydney and kept on going despite the downpour. Naomi and Liev took their sons, Sasha and Samuel, Down Under for a family vacation with their Watts relatives. The family touched down about two weeks ago and have since fit in fun beach days and a celebration in honor of Australia Day. The getaway has also included some work for Naomi. She and costar Robin Wright started filming The Grandmothers Monday at Seal Rocks, four hours north of Sydney. The movie is under the direction of Anne Fontaine, who was behind 2009's Coco Before Chanel.
