Katie Cassidy Returning to Gossip Girl

Katie Cassidy will return to Gossip Girl for The CW soap's final episode, TVGuide.com has confirmed.

There's no word on what prompts her character Juliet Sharp's return, but she was last seen in Season 4 of the show, when she dated Nate (Chace Crawford) and devised a plot to bring down Serena (Blake Lively), who had had an affair with Juliet's brother Ben (David Call).
