Naomi Watts and her boys shared a mommy-and-me and music-filled afternoon at the park in NYC yesterday. The mother of two showed her youngest, Samuel, that she was listening to Lady Gaga on her iPhone as he had a quick snack between rides on the slide. The trio are back on the East Coast after spending some time together in LA around award season. Dad Liev Schreiber wasn't along for their latest outing, but the whole family had a lot of fun during their stint in California, hitting up a local amusement park and heading out on bike rides together. Their latest busy day out had at least one member of the Watts-Schreibers ready for a nap, as Sasha took a snooze in his stroller on the way home.
