Party-Hopping Blake Lively

This girl is so popular she has to cut one party short just to attend another party. And Blake Lively had her hands full of social engagements last night.

The Gossip Girl hottie began the night by attending the New York City premiere of “The Dark Knight” held at the AMC Loews Lincoln Center cinemas. Joined by boyfriend/costar Penn Badgley, Miss Lively looked gorgeous in a black satin romper dress with a plunging neckline teamed with a pair of shiny heels.

From there, Blake headed over to the Vitaminwater Celebrates in Style with the Best in Baseball and Music event. And once again she pleased the paparazzi with her stunning style and killer smile.

With a little over a month until the new season of Gossip Girl hits the airwaves, we can expect to see Miss Lively at more and more promotional appearances.
