Gossip Girl 5x13 - 100th Episode Sneak Peek

We've got a sneak peek at Blair's Wedding to Prince Louis and the 100th episode of Gossip Girl. Will she really walk down the aisle though -- or will Dan or Chuck be able so stop her? We've got photos from the new episode plus details on Serena and Dan's relationship and possible reconciliation. 

I just received pictures from the CW of Serena dressed as Marilyn Monroe in a hot pink gown, surrounded by the Upper East Side fellas. In one pic, we see Blair enter the scene looking just like Audrey Hepburn. I'm told this is a dream sequence that will show Serena & Blair Vying for DAN'S affection and love. Watch the 5X13 GG sneak peek here and let us know what you think Blair will do!
