In case you missed it, Blair called it quits with Chuck on this week's episode of Gossip Girl. All good things come to an end for our upper east siders (often after just a few episodes), but is there still a chance for these two? The latest promo for the show seems to think so, paying an over-the-top homage to Chuck and Blair's tortured love story. While their initial hookup back in season one is one of my favorite episodes, I'm not sure that Chuck and Blair are my all-time favorite couple. Who do you think is the best couple Gossip Girl has ever seen?
