With the season premiere of Gossip Girl hitting the airwaves Monday, Blake Lively was hot on the promotional trail yesterday (August 28) with a stop by the Late Show with David Letterman.

The “Sisterhood of the Traveling Pants” cutie arrived at the Ed Sullivan theatre in Midtown Manhattan, stopping outside to hang with fans, pose for pictures, and sign some autographs.

And Miss Lively looked leggy in a sexy grey minidress with black heels and a black handbag as she made her way inside.

After her interview, Blake reemerged from the theater, this time looking even more glamorous in a black blue and grey cleavage-baring dress teamed with a pair of black high heels.
