Lindsay Lohan To Guest-Star On Gossip Girl?!?

SPOTTED: Lindsay Lohan in the charming company of Ed Westwick.
Better guard yourself, Blair Waldorf…
Cuz from the looks of this photo, LiLo might be catching the infamous Chuck Bass before you can say O-M-G.
Ha! Okay… srsly now… what in the world is going on here??
Is Linds merely partying with her Gossip Girl crush? Or are they talking work.. as in… guest-role in the last season of GG work… ????
She posted the photo to her Twitter account with the vague message:

“#www.whatshethinking.com -that’s a good site idea, isn’t it? Wouldn’t all of us girls like to know!”

Hmm… we’ll keep our eyes glued on this one.
Stay tuned, Upper East Siders…
