Blake Lively & Leighton Meester: Sexy on the Set

Getting down to work on their show “Gossip Girl,” Blake Lively and Leighton Meester were spotted on the New York City set today (December 14).

The CW costars filmed scenes outdoors, one of which involved Blake and Leighton getting into an argument just before Lively hails a cab and drives off in a huff.

In between takes, Ms. Lively entertained herself by taking pictures of a man walking his dog while wearing a New York Yankees ballcap.

Speaking of dogs, Blake brought both her dog Penny and her boyfriend Ryan Reynolds’ beloved pooch Baxter with her to the set yesterday.
