Today’s near-random photoset of near-exclusive photos comes to you from the Brooklyn set of Gossip Girl, where Blake Lively’s Serena was beating the royal crap out of Leighton Meester’s Blair for the last setup of the day.

The two actresses seemed to be having a good time, until cameras rolled.

Minor spoilers for Season 2, we guess? Though the cast has been at it long enough in the Brooklyn streets to put this episode mid-season or further.

We might not know what the girls were fighting about, but who cares. It’s a catfight, and that makes it worthy of the photoset!
