OMG! GOSSIP GIRL HITS 100 EPISODES! — The much-anticipated 100th episode will open with a musical dream sequence featuring Serena (Blake Lively), Blair (Leighton Meester), and all the men in their lives (Penn Badgley,Chace Crawford, Ed Westwick, and Hugo Becker). Also, while Chuck wrestles with the reality that Blair is about to walk down the aisle with Prince Louis, the return of Georgina Sparks (Michelle Trachtenberg) might make the royal affair a royal disaster. Kelly Rutherford and Matthew Settle also star. Mark Piznarski directed the episode written by executive producer Joshua Safran (#513).

While we’re not sure why B thinks she even loves Louis enough to marry him at this point (seriously, is it only obvious to us that she maybe never even did?), we have a feeling with all this Dan/Chuck/GEORGINA action in the mix, something will stop Blair from making such a grave mistake... we hope!
