Naomi Watts and Liev Schreiber chalked up another afternoon of fun in NYC with their boys, Sasha and Kai, yesterday. Naomi was solo on her bike, as both sons were passengers of Liev's for a ride to a nearby park. The family outing is nothing new for the Watts-Schreiber clan, who spent time together earlier this week as well. On Tuesday, Naomi planted kisses on both Sasha and Kai during a rainy day stroll around the Big Apple. Naomi has been reunited with her family after returning earlier this week from Madrid, where she premiered her latest movie, The Impossible.
