Naomi & Liev Securely Jet-Set with Sasha & Kai

Naomi Watts and Liev Schreiber were spotted taking their two sons, Sasha and Kai, through security for the departures at LAX yesterday. The family of four is probably joining Angelina Jolie and the Jolie-Pitt gang in Japan for the Japanese premiere of Salt, which stars Angelina and Liev. Sasha, who is getting a lift from Dad, should feel extra special because yesterday was his third birthday!

What is a better way to spend your special day than with your mom, dad and baby brother? Other than getting to go on a vacation, of course!

Luckily for Sasha, he gets it all! Happy birthday, Sasha! We hope you had a great day!
