As Gossip Girl fans know fairly well, Michelle Trachtenberg excels at playing a slightly unstable individual.
And CBS viewers will soon learn this for themselves, as the young woman behind Georgina Sparks has landed a role on Criminal Minds Season 8.
As first reported by Entertainment Weekly, look for Trachtenberg to guest star on an early 2013 episode of the hit drama as stalker who goes a bit bananas after being denied a job.
Moreover, according to the same report, the installment in question will focus on Reid’s new love interest. No, not Trachtenberg's whack job.
