The rich kids of the Upper East Side said their goodbyes on Monday, 17 December in the US. Over its six seasons,Gossip Girl did not start a television revolution, but it did manage to become a social phenomenon, especially among teenagers.

On 17 December, the CW network aired the conclusion of the adventures of Serena van der Woodsen, head of a circle of high school friends, and later graduates, in the most chic Manhattan neighborhood, with the episode New York, I Love You XOXO, a reference to the signature used at the end of each episode by the narrator, the secret Gossip Girl.
