Some other tidbits and teases from executive producers Stephanie Savage and Josh Schwartz:

— A giant female music personality is close to signing on for a guest role. "She'll not only preform an original song but will also act with the characters," Savage teases. "She's both new and iconic." (Madonna, perhaps?) Look for the performance during episode seven, right in time for November sweeps.

Since Britney said that she loves the show, that makes her a candidate. What y'all think?

I would say GaGa but she's already made an appearance so my next guess would be Brit.

Britney isn't exactly new though now is she.

"She's both new and iconic."

As much as I'd love to believe it's Britney, she's been around for more than a decade, she's hardly "new".

GaGa made an appearance? I just thought they did an episode. Plus Britney isn't "new". It has to be GaGa.

*EDIT*

Maybe Rihanna?

Well Britney is new...

or Katy Perry at a push.

Britney at gossip Girl would be amazing!!

i read a rumour last week about Britney and Gossip Girl

LMFAO.

I definitely read Glee . Oh okay, never mind that then.

Ah yes, possibly.

It could be Ke$ha. She's new and iconically all messed up.

Katy Perry? Her team is putting her EVERYWHERE. I knew the moment they got Esquire to name her the sexiest that this era would be EXPLOSIVE.

Well since she's new it's not logical it's Britney unless he is tryin' to create hype and throw us off so we won't know who it is.

I would say Ke$ha, Katy, thought I don't think Katy will do somethin' like that for some reason.
