This Gossip Girl video was just sent to us and we guarantee you'll enjoy it.
The upcoming brawl between Blair and Serena - we think - happens at a party for students interested in Yale. We've seen pictures of the incident being filmed, but now some video of it (from the set in Flatbush, Brooklyn, shot by a passerby) has surfaced!
A lot of the dialogue between them is hard to decipher, but as the frenemies bicker on the porch, there are clear shouts of "You shut up!" "No, you shut up!"
Then they go at it in a crazy display of pushing, shoving, hair-pulling and, eventually, one of them getting spanked (!) - which elicits laughter from the crew!
