In celebration of Gossip Girl's highly-anticipated 100th episode Monday night, in which Blair's highly anticipated wedding to Prince Louis finally takes place (whether she goes through with the "I dos" is a different story entirely) the CW has put together a very special promo in honor of the queen herself.

There are a whole lot of Chair moments in this Blair-centric promo. Just saying.

It's a fun promo in any case, and brings back a lot of fond memories. Visit our Gossip Girl spoilers page for all the scoop on "G.G." and beyond, then get excited and nostalgic with the Blair-themed ad below:
