Warning: Spoiler alert!
A very good Gossip Girl source has just revealed exclusively to PerezHilton.com some juicy news!
There's gonna be some girl on girl action on GG coming up on the show.
Guess the two who are gonna get it on!
We'll give you a hint: one of the girls is blonde.
Oh, screw it: It's Serena and Georgina (Michelle Trachtenberg)!
