A baby, a breakdown and a cat fight! Which Gossip-worthy moment left YOU totally speechless?

BFFs, the night we’ve  been waiting for all summer has finally come — the fourth season of Gossip Girl is here! Many questions were left unanswered after last May’s finale, and in typical Gossip Girl fashion, the Sept. 13 premiere shocked me from beginning to end. Since Serena (Blake Lively) and Blair (Leighton Meester) have left the Upper East Side to conquer the streets of Paris for the summer,  they’ve been swooning over Chanel shoes and cute boys. But B and S have a harsh reality to face when they return to the streets of Manhattan.

Here are our favorite OMG moments from tonight’s episode:

1. Georgina has a baby!

We were skeptical when Georgina Sparks (Michelle Trachtenberg) showed up “pregnant” in the third season finale. But now that it’s confirmed she was pregnant and has a baby as proof, we just have one question: Is Dan Humphrey (Penn Badgley) really the daddy?

2. Chuck Bass is alive!

This was by far the biggest OMG moment of the night for me! Last time we saw Chuck Bass (Ed Westwick), he was bleeding to death after being shot in an alley. Now we know he’s alive and well — very well, actually. He’s romantically involved with a mysterious blonde, and he’s en route to Paris! Uh-oh…

3. Serena decides to go Columbia!

After a year of putting college aside, I’m so glad to see that Serena has finally come to her senses, choosing to enroll at Columbia University in the fall. And best of all: BFFs Serena and Blair will be reunited once again!

4. Blair admits she misses Chuck!

Blair acts all tough and pushes BFF Serena into a fountain, but she eventually lets down her guard and confesses she’s still totally hurting post-breakup from Chuck!

5. Who is Juliet Sharp?

After Nate Archibald (Chace Crawford) hears that Serena will be back in NYC for the school year, he clings to a new mysterious girl named Juliet Sharp (Katie Cassidy.) But it doesn’t look like it’ll be a drama-free love connection after catching a glimpse of Juliet’s room decked with newspaper clippings of the the Gossip Girl clan.

So what did you think BFFs? Were you totally shocked throughout the episode as I was? Drop me a comment with your biggest OMG moments from the night!
