OK, yes, I know I was just talking about Gossip Girl. But forgive me for going back to the well so soon, because I can't let this day go by without telling you about the most awesome stunt casting/crossover idea I think I've ever heard: Blake Lively and Leighton Meester will guest-star on 30 Rock, playing high school classmates of Liz Lemon's in an episode where we find out Liz was actually a mean girl in high school.
No word on whether Blake and Leighton's characters will also be mean girls — or whether they'll be victims of Liz's nastiness. Either way, this just proves that 1) 30 Rock is awesome, and 2) these Gossip Girls (or their agents) are pretty savvy themselves.
But oh, the awesomeness doesn't end there. Since the episode revolves around Liz's high school reunion, we'll see adult versions of those two characters, too — and the producers are reportedly talking with Robyn Lively (yes, Blake's sister, of Teen Witch fame) about playing one of them. See? So fantastic!
So, here's a question: What actress should play the younger, meaner Liz Lemon?
