Executive producer Joshua Safran announced that he would be `` pulling out all the stops '' to make the 100th episode of the show special, which is expected to air in January. On the date of the season premiere, the show used footage of the New York cityscape that showed the World Trade Center before the September 11 attacks. Footage containing the World Trade Center have been omitted by films and TV shows such as Sex and the City and The Sopranos to honor individuals who died in the attacks. The network has not responded to criticism regarding the usage of the footage. Despite dwindling ratings, series executives are confident the show will be renewed for a sixth season. Head of Warner Bros. Television, Peter Roth is also confident that the show will return, stating, `` I ca n't really say at this point, but I would hope and expect that there would be at least another year -- if not years -- to come. '' Later on, executive producer Stephanie Savage hinted that a sixth and final season is likely. `` We 're not writing a series finale this year, '' said Savage. She added `` I checked in with the bosses to make sure we 're not shooting ourselves in the foot '' and said the cast contracts run out at the end of the next season so `` that feels like probably an organic ending point ''. St. Vincent performed `` Cruel '' and `` Cheerleader '' from her Strange Mercy album during the Valentine 's Day episode. Cast Diana 's entrance on the Upper East Side will change the lives of all our characters -- including and especially, Gossip Girl herself. -- Stephanie Savage and Joshua Safran on Liz Hurley 's introduction.

Gregory as a friend of the real Charlie Rhodes ( Ella Rae Peck ). Cobra Starship 's Gabe Saporta made a cameo in season 5 finale. Plot I feel like if you 're a fan of the show and you 've been watching from the beginning, you 're going to feel rewarded. But I also feel like if you 're tuning in after a long time, I think you may feel like you 've missed a lot, but we really try to hit on everything that 's happened since ( early on ). I 'm very proud of it. -- Joshua Safran on the series ' 100th episode milestone. Season five opens in Los Angeles, where a vacationing Chuck and Nate decide to visit Serena, who is working on a film set.
