Simon & Schuster publisher Jonathan Karp made a guest appearance on the season four finale of Gossip Girl last night.
Karp (pictured, via) negotiated over a manuscript deal with one of the main characters. Posters featuring Chris Cleave‘s Little Bee and Incendiary decorated his office.
SPOILER ALERT: Readers know that this incident did not take place in the Gossip Girl book series. Author Cecily von Ziegesar didn’t seem to mind. In fact, she made a quick cameo in the same episode.
