Naomi Watts: Pantene Celebrity Ambassador!

Naomi Watts and her younger son, Samuel, arrive back at their apartment on Wednesday (May 25) in NYC.

Earlier in the day, the 42-year-old actress went biking with her longtime love, Liev Schreiber, who on Thursday was spotted giving older son, Sasha, a ride on his shoulder.

Naomi was recently named one of Pantene’s new celebrity ambassadors and will be the face of its Flat to Volume collection.

“Since I became a mother, the time I have for myself has shrunk dramatically. Also, I have never been able to do my own hair. So I am thrilled with Pantene because the quality of the products helps me get the volume I want with very little effort at all,” she said in a statement.

FYI: Naomi is wearing a Twenty8Twelve tee.
