It's the teen-drama crossover event of the century! Blair Waldorf (Leighton Meester) and Seth Cohen (Adam Brody) are allegedly engaged.

The Gossip Girl actress and The O.C. actor met on the set of the indie film The Oranges which filmed in 2011, but didn't begin dating until February of this year after they started "hanging out" in early 2013.

They will also appearing together yet again in the upcoming film Life Partners.

News of their engagement was confirmed to Us Weekly, who usually have a pretty good track record with this sort of thing.

We hope Chuck Bass is cool with all this.
