You'd think that launching a new TV show — Showtime's United States of Tara — would be enough to keep Diablo Cody busy these days. But at the TCA press tour this morning, the Oscar-winning writer had something else on her mind: her upcoming guest spot on 90210.

"I don't know if they want me talking about it — I'm sure they're deeply ashamed, but I'm very excited," she said. "I've written about 90210 in Entertainment Weekly several times because I'm completely obsessed with the show, both incarnations old and new. They actually called and said, 'Would you like to be on 90210?' And I said,' I don't care if you want me to wear a bear suit, I'll do anything on 90210.'"

So, will she be wearing a bear suit for the spot, which she's filming at the end of the month? Cody said she didn't know — but a reporter told Cody she'd heard she'd be playing herself and working with Tori Spelling in an episode directed by Jason Priestly.

"They have not told me this!" she exclaimed. "Oh, I swear to God, I have to go outside. I did not know that. I love Jason Priestly, I love Tori Spelling. I'm so psyched!"
