Trachtenberg, who was born in Manhattan and grew up in Brooklyn, told the XOXO podcast with Jessica Szohr that she knew a lot of people from the Upper East Side, in her 20s, who were “very similar to the Gossip Girl characters and involved in that world,” adding “and some were actually more scandalous than the show portrayed.“
