Leighton Meester & Ed Westwick's "Gossip Girl' Workday

Teaming up for a full day of filming, Leighton Meester and Ed Westwick took to the set of "Gossip Girl" in New York City today (October 24).

The CW castmates dressed in their usual super-stylish garb while on the Madison Ave shoot, as "The Roommate" actress sported an eccentric all-blue ensemble while Ed donned a funky plaid suit and sleek gray overcoat for his time in front of the camera.

Meanwhile, musically-inclined Leighton recently revealed her love for Brit beauty Cheryl Cole, thanks to her "Monte Carlo" co-star Selena Gomez.

Meester told press, "We had a blast singing Cheryl Cole and Katy Perry songs. Selena had a few of Cheryl's songs on her iPod, but we downloaded some more as well. I love Fight For This Love. It's great, although we'd change the words to make us laugh. Over lunch or breakfast, you'd hear us singing things like, ‘you've gotta jump, jump, jump, jump, jump for this bread’. There's another track about being drunk in love or something ... I love that one, too. Cheryl Cole's great.”
