Cranking out another drama-filled episode of “Gossip Girl,” Blake Lively and Ed Westwick were spotted on the set in New York City today (December 1).

The “Sisterhood of the Traveling Pants” starlet gave a flirty smile to shutterbugs as she walked down the sidewalk in between takes.

Meanwhile, Mr. Westwick kept it cool in sunglasses and a snazzy grey overcoat as he endured the falling temperatures.

Coming up on the next episode of “Gossip Girl,” titled “Riding in Town Cars with Boys,” “Lily throws Charlie a party to officially introduce her to New York society. Meanwhile, Charlie's ex-boyfriend, Max (guest star Brian J. Smith), throws a wrench into Charlie's future as an Upper East Side princess. Dan decides it may be time to tell Blair the truth about his feelings for her.”
