It's here! It's finally here!

Gossip Girl's 100th episode is just days away and everyone is excited...including New York City Mayor Michael Bloomberg, who was on the show's set today to give the CW drama their own day: Yes, it's officially Gossip Girl Day! Shall we celebrate with some sneak peeks of the 100th episode and interviews with Blake Lively, Leighton Meester, Penn Badgley and Ed Westwick reminsicing on the last five years? We shall!

So why does Georgina (Michelle Trachtenberg) decide to crash Blair's wedding? And what does Meester want to see happen with Blair?

"I can't even believe it's been five years. It's so crazy," Lively says of the milestone achievement. "It doesn't feel like we've done a hundred because it's been so enjoyable."

Meester agrees, but adds, "I feel like in one way I've been here my whole life, so it's like, oh my god! It's the 100th episode! It seems like an entire lifetime, but at the same time it's happened so fast. It just seems like we came here yesterday." With so much going on with Blair in the 100th episode, Meester says, "I kind of just want to see what happens with Blair. I want to continue to live that other part of life. It feels like a little alter ego of my life that I get to explore and growth with."

For Badgley, he's grateful for the opportunities that Gossip Girl has provided to him and his castmembers. "It's been a very interesting experience and it's given all of us a lot of what we have now, both on and off camera," he says. "It's been a significant experience; massive and definitive for all of us."

Westwick echoes his costars' sentiments, saying, "It's quite an achievement, I have to say. It feels like it's happened so quickly."

And just to tease fans a bit, Westwick adds in, "We're still going strong so I'm looking forward to the next 100! We'll see what happens."
