Naomi Watts: Fun In The Sun With Sasha

Naomi Watts took advantage of a sunny day to whisk son Sasha, 3, out to a park in New York City on Tuesday (August 3). And lucky boy – he's still light enough for mom to give him a piggy-back ride.

Little brother Kai, 1-1/2, must have stayed home with dad Liev Schreiber.

Even running around a park, Naomi still looks great. No wonder she's been tapped to be the new face of Ann Taylor's Fall 2010 ad campaign.
