Serena is linked to Steven in a least way that she could expect. In the next episode of "Gossip Girl", the pair decide to reveal their romantic histories so they aren't surprised by anything, but neither is prepared for what they uncover.

Steven is uncomfortable that Serena once hooked up with Nate, who is currently dating his daughter Sage. Serena, on the other hand, is surprised to learn that Steven slept with her mother Lily.

Meanwhile, Chuck's continued investigation into his father's dealings leads him to an unlikely event with Manhattan's elite, where he hopes to find the one person who can tell him the truth about Bart. With The Spectator in jeopardy after Dan decided to publish elsewhere, Nate must make a difficult decision to keep it in business.

Also in "Portrait of a Lady Alexander", Georgina pushes Dan to choose a worthy person to date to boost his image, but he finds himself drawn in a different direction. The episode will air Monday, October 29 at 9/8c on The CW.

As the cast has wrapped up the filming for the final season of the teen drama series, they recently threw a farewell party. Chace Crawford, Blake Lively, Ed Westwick, Leighton Meester and Michelle Trachtenberg were among those attending the event, which seemingly turned into a food fight.
