Blake Lively: Ryan Reynolds' Dog Sitter!

Blake Lively and Leighton Meester continue to film more scenes for Gossip Girl on Wednesday (December 14) in NYC’s Lower East Side.

The 24-year-old actress bundled up in a blue White + Warren scarf, while Leighton, 25, kept warm in a bright green coat with a Milly skirt.

In between scenes, Blake played with and watched over beau Ryan Reynolds‘ dog, Baxter.

The day before, Blake was spotted arriving on set with both Baxter and her own Maltipoo, Penny.

FYI: Leighton is wearing an Autumn Cashmere scarf in Petunia.
