Blair Waldorf's Wedding Dress & More Enviable Fictional Bridal Gowns (PHOTOS)

Spotted: Leighton Meester on the streets of the New York City stranded in a wedding dress.

In true "Gossip Girl" fashion, it seems that Blair Waldorf's fairytale wedding, to air in January, takes a turn for the worse as Blair makes a dramatic flee from the altar. A royal runaway bride? Quelle horreur!

Sad as it might be, we couldn't help but squeal in delight over the dress. Leighton -- er, Blair Waldorf looked every bit the royal bride in a gown (possibly) created by Vera Wang, according to Grazia Daily (the actress is the face of Wang's "Lovestruck" fragrance, after all). The princess-style look was topped off with peep toe pumps, tousled waves and a sparkling tiara befitting her royal-to-be status.

First Bella, now Blair? We couldn't help but compare... and conjure up more of our favorite fictional bridal moments.

From Sarah Jessica Parker playing Carrie Bradshaw in Vivienne Westwood to Amanda Seyfried in "Mammia Mia!", here's the briefest of rundowns of our favorite on-screen wedding dresses.
