blair waldorf wedding run 'Gossip Girl' pics: Blair is heading down the aisle... and running out the door?We never thought this day would come! Photos have emerged from the NYC set of “Gossip Girl” — and yes, Upper East Siders, the royal wedding is on!

Let’s be honest. None of us actually think of the excruciatingly boring Prince Louis (Hugo Becker) as a viable love interest for the vibrant Blair Waldorf (Leighton Meester). It’s either Dan (Penn Badgley), Chuck (Ed Westwick) or nobody.

This photo from the set of the series’ 100th episode, tweeted by fan @Tara_panera, certainly paints an interesting picture. Meester is dressed in her royal wedding finery – but Blair is heading out the door of the church all by herself, not on the arm of her prince.

Do we have a potential runaway bride? And just who is she running to?

It’s also important to note that Blair is baby bump-free. We guess it’s (vaguely) possible that she might not be showing yet — those Waldorf women have all the luck — but we’d wager on a sadder fate for the fetus.

What do you hope to see happen in Episode 100? Chair? Dair? …Blouis?
