Hey there, I'm Karli Bulnes. A bridal gown wearing Blair Waldorf has been spotted on the run — See the first photos in PopSugar Rush!

Wedding bells or cold feet for Blair Waldorf? The first photos of Leighton Meester wearing her wedding gown have us wondering if she'll make it to the altar! While filming on Monday, a tiara-topped Leighton was seen sprinting across the street in high heels, no less. The runaway bride theory isn't too much of a stretch though, especially after watching this week's episode — Louis was away, so Blair made it her mission to prove that Chuck isn't a changed man after all. Blair believed she proved her point when Chuck kissed her, but it turned out Mr. Bass was only playing along to help her move on with her Prince. Could Chuck's move actually upset Blair's road to the royal wedding?

And another noteworthy observation... there seems to be no sign of a baby bump! Gossip Girl airs Mondays on The CW.
