The TCAs kicked off this weekend in Pasadena with everyone buzzing about Jay Leno and Conan O'Brien's future at NBC. Before that news, on Saturday Peter Facinelli chatted about Nurse Jackie, Twilight, and Twitter. We also got to know the adorable new cast of Life Unexpected, followed by the hot Vampire Diaries — check out a sneak peek of what to expect next. The cast couldn't stop gushing about how much they love working together, and Nina Dobrev was even celebrating a very special 21st birthday. When asked about the rumors that we will see werewolves in the upcoming season, Paul Wesley told us he doesn't know but thinks it would be a fantastic idea.

On Sunday it was all about NBC — the Parks and Recs cast had the whole room laughing, joking about everything from Twitter to the show's critical turnaround in season two, and when asked about a possible crossover with 30 Rock, Amy said, "Well I want to do something with Lost, but they're not NBC." Jerry Seinfeld also took the stage to introduce his new show The Marriage Ref, which follows ordinary couples who need help solving arguments and already has celebrity guest lineups including Alec Baldwin, Tina Fey, and Eva Longoria. Of course Jerry couldn't get away without questions on Jay and Conan, to which he said, "I hope Conan stays on NBC, I think he's terrific." We also finally got a chance to check out Ron Howard's Parenthood, which looks great despite cast changes and drama.

At night the stars from NBC hit the red carpet to celebrate the network. Amy Poehler, Michelle Trachtenberg, and Rashida Jones looked beautiful in black, while Community and Mad Men star Alison Brie added a little pink to her red carpet look. We spoke with Alison, who was excited to talk about Jack Black's appearance this Thursday's episode and what she hopes we see from Trudie in Mad Men's next season — more on that later from Buzz. The casts from The Office, Heroes, and Chuck also mingled with each other over cocktails. There's lots more to come, so stay tuned for updates on Twitter.
