Naomi Watts & Kai Head Home

A sleepy yet smiley Naomi Watts prepared to depart Phuket International Airport on Monday (February 14) with her youngest son, 2-year-old Kai, after a long day wrapping her latest project, The Impossible, in Khao Lak, Thailand.

On Sunday afternoon (February 13) Kai was spotted enjoying a piggy back as he and his talented mama arrived on the set.

Naomi’s partner, actor Liev Schreiber, must be at home in New York City with their 3-year-old son, Sasha.

Recently, the family of four had a blast vacationing in Naomi's native Australia.
