Mean Girls Meet Mean Girl

'Gossip Girl frenemies Leighton Meester and Blake Lively have closed a deal to guest-star in a November sweeps episode of NBC's increasingly stunt-happy 30 Rock, sources confirm to me exclusively. The dynamic duo will play — prepare to laugh 'till you piddle — former high school classmates of Liz Lemon's in a flashback sequence that reveals a shocking and deeply ironic truth about Tina Fey's morally superior alter ego: She was a Mean Girl!'

The girls are cute, but "30 Rock" and Fey better go easy soon on the gimmicks–that can backfire quickly and instantly ruin the show's quirky nature. Better watch out for jumping the shark. Just stick to quirky, funny, behind-the-scenes, industry-satire comedy on "30 Rock" and forget the celebrity and guest actor stunts–that's what will ruin the show, not improve it. Jennifer Aniston is smart, funny and beautiful–but we really don't need her on "30 Rock." These young girls from this other dumb show are cute, but we don't really need them on "30 Rock," either. Tina: You already have a talented comedic crew of people crowding your show. USE THEM. You do not need any of these goofball celebrity stunts on the show. USE THE PEOPLE THAT YOU HAVE THERE ALREADY. Don't jump that shark just yet.
30 Rock jumped the shark during the pilot episode!
Hooray! Total media dominance for my favorite show.
