Rachel Bilson: 'BFF, Baby' & Puppy!

Rachel Bilson continues work on her upcoming comedy BFF & Baby on Friday (November 5) in Los Angeles.

The 29-year-old actress was spotted leaving her trailer juggling a cold beverage, script, and an adorable puppy!

Co-star Krysten Ritter, who’s been tweeting and sharing twitpics from the film’s set, also spent time with a pet — a feline friend!

When the ladies weren’t working, they received a surprise visit from Lauren Conrad, who reportedly filmed a cameo for the flick last month.

FYI: Rachel is wearing a “Milla” tee by Market.
