Taylor Momsen and Willa Holland teamed up to shoot scenes for Gossip Girl

The producers of the hit CW drama "Gossip Girl" keep on adding more sex appeal to the new season. And this time, it's in the form of former "O.C." actress Willa Holland.

Holland was joined by Taylor Momsen on the show's New York City set yesterday (September 30) as they filmed scenes for a new episode.

Miss Momsen smiled for the paparazzi, sporting a flirty grey printed babydoll dress with black stockings, while Willa rocked a graphite minidress with a black cardigan and some funky fishnets.

Holland's character Agnes was imported to the show to cause problems for Momsen's Jenny Humphrey and her position at Eleanor Waldorf Designs. She's scheduled for at least three episodes this season.
