Is TV’s most tumultuous lady-friendship about to hit the skids again?

Cameras caught Blake Lively (Serena) and Leighton Meester (Blair) on set Wednesday (December 14) lookin’ none too pleased with one another. IN FACT, onlookers reported that Serena stormed away from Blair, as B pleaded with her, saying, “It’s not what it looks like.”

Cue a collective eyebrow raise! Might this be drama of the DANIEL HUMPHREY variety?

We’ll concede that these two don’t have the most consistent of BFF relationships, and that they’ve been known to quarrel over dudes before (NAAATE). But if S is taking out her aggression over wasting her opportunity with Dan on Blair, while Blair’s life is (already) a WRECK of epic proportions... well... that just doesn’t seem right.

Then again, what else could it be? Perhaps we’ve unearthed some fallout of Georgina Sparks-schemin’? Hmm...

(Off-topic side-note: Sometimes we wish the UGGs that Blake and Leighton wear to film would make it onto the show. Just for a minute... with sweats.)
