It was Bring Your Baby to Work Day for Sarah Michelle Gellar -- who kicked off shooting her new TV show with daughter Charlotte on set!
Gellar, who hasn't been on camera for TV since "Buffy the Vampire Slayer" went off the air in 2003, was filming the pilot "Ringer" yesterday in NYC -- and was spotted leaving the set with her adorable 18-month old with husband Freddie Prinze Jr.
The show revolves around a young woman on the run from the mob who poses as her twin sister to try and hide -- but finds out people are after her sis as well. Gellar will play both sisters.
