Naomi Watts and son Sasha Pete, 3, attempt to hail a cab on Monday while making their way through chilly New York City.
The actress, 42, and fiancé Liev Schreiber recently returned from a trip to her native Australia with Sasha and younger son Kai, 2.
“I love being a mum. I just love it,” Watts says. “It’s the most rewarding thing, but the most challenging thing.”
