Taking care of some promotional duties, Leighton Meester was spotted arriving at the Ed Sullivan Theatre to tape her appearance on "The Late Show with David Letterman" yesterday
The "Gossip Girl" cutie looked flirty in a one-shoulder silver blouse along with black trousers and a massive black belt as she posed for the paparazzi
From there, Miss Meester headed over to the series premiere of "The Day Before" to hobnob with industry bigwigs and a few fashion designers.
"The Day Before" is a documentary-style four-part series (debuting today on the Sundance Channel) that gives an inside look on the world of fashion designers
