On May 11, 2012, it was announced "Gossip Girl" would return for a shortened sixth and final season, which premiered on October 8, 2012. During the CW upfronts, network president Mark Pedowitz said the number of episodes had not yet been decided and could consist of 10 episodes with a retrospective, meaning it would end before Christmas.

The season premiered with 0.78 million viewers tuning in, marking a series low for the show. The following week, there was a further drop in viewership, with only 0.76 million viewers, once again breaking the record for series-low ratings.

On October 29, 2012, the episode "Portrait of a Lady Alexander" was postponed due to the impact of Hurricane Sandy on the Eastern Seaboard. Widespread power outages led to the decision of pushing the new episode back a week and re-airing the previous episode, "Dirty Rotten Scandal".
