SAMUEL KAI SCHREIBER

Salt star Liev Schreiber was all smiles on his 45th birthday as he went for a bike ride with his son Kai in New York City on Thursday (October 4). The adorable 3-year-old sat on the front of dad’s bike while the duo enjoyed the beautiful autumn morning.

In the evening, Liev Schreiber posed for pics with a gorgeous blonde – his 3-year-old son Kai with partner Naomi Watts – as the pair attended the Unveiling of the Revitalized Public Theater at Astor Place in New York City.
