The whole Watts-Schreiber crew took a stroll through NYC yesterday. Liev carried Sasha on his shoulders while Naomi pushed Samuel and held onto their dog's leash. The foursome picked up frozen yogurt from Pinkberry before continuing on their Summer stroll. It's been a fun season for the family since the Watts-Schreibers got away to the Hamptons once Naomi took care of some red-carpet duties. She joined pal Liv Tyler for the unveiling of Stella McCartney's latest collection and also stepped out for a bash thrown by Thierry Mugler. Naomi will soon be back in the spotlight when she starts promotions for J. Edgar, which hits theaters in November.
