Naomi Watts and Robin Wright lounged atop the sand on the set of The Grandmothers in Sydney yesterday. Robin wore a bikini for the scene while Naomi covered up in a one-piece swimsuit. Naomi traveled to her native Australia with her family last month. She went to Bronte Beach with partner Liev Schreiber and sons Sasha and Samuel, made an appearance at Centennial Park, and was spotted jogging with Liev earlier this week. Naomi's since switched gears to work and has spent the last few days filming with Robin. The Grandmothers is one of Naomi's many projects, since she also recently signed on to portray Princess Diana, saying, "It is such an honor to be able to play this iconic role."
