There's going to be a shakeup on the Upper East Side!
Although Gossip Girl
has been renewed for a fifth season, not all its fashionable characters will be back: Taylor Momsen
, who plays Jenny Humphrey, and Jessica Szohr
, who plays Vanessa Abrams, will not return as series regulars, PEOPLE can confirm.
The news may not come as a total shocker – Momsen, 17, hasn't appeared
on many recent episodes, and in season 4 the character played by Szohr, 26, left town.
Still, both stars may make guest appearances in season 5 – and Momsen fans can check her out when she performs with her rock band, The Pretty Reckless.
