Naomi Watts Works Out After Her Fun Girls' Night Out

Naomi Watts carries her bottle of Fiji Water while leaving the gym on Thursday morning (January 30) in Santa Monica, Calif.

The 45-year-old actress made sure to work on her fitness to burn off calories gained from her girls’ night out the evening before at Mr. Chow restaurant in Beverly Hills.

Earlier in the week, Naomi‘s longtime partner Liev Schreiber was seen heading out for lunch with Sarah Michelle Gellar, who he worked with in the 90s movie Scream 2. Always fun to see old co-stars reuniting!

FYI: Naomi is wearing an Inhabit Cashmere/Linen Marl Long Cardi.
