On Gossip Girl (it's cool; you can admit you watch it), Michelle Trachtenberg plays Georgina Sparks, a conniving, Upper East Side Queen Bee that likes to cause trouble. It seems that her guest appearance on Weeds this season will offer more of the same. Except for the Queen Bee stuff.

Trachtenberg has been cast on the New York-set seventh season of the Showtime series as a low-level pot dealer and rival to Nancy Botwin (Mary-Louise Parker). Not only that, Trachtenberg will allegedly romance Nancy's son Silas (Hunter Parrish). Weeds debuted on Monday night.
