Best of luck! Here's this week's Gossip Girl Caption Contest pic ...

Below are a dozen promotional photos for the November 30 episode of Gossip Girl, "Treasure of Serena Madre." There is no new episode this coming Monday.

It's Thanksgiving, as you can probably tell, and there's going to be lots of drama as Serena ends up at dinner with Tripp and Maureen for reasons unknown.

We'll also see what happens with D and V, and there are some cute Chair photos here to make fans of that couple very happy. Click to enlarge the pics ...

On Gossip Girl, Leighton Meester plays Blair Waldorf, one of our favorite characters, a mostly proper young woman who only rarely lets her guard down.

When she does let her sexy side shine, though, Blair certainly knows how to channel her inner bad girl. In this photo shoot with GQ, Leighton does too:

Leighton Meester is a good girl gone bad!

The 23-year-old actress and aspiring singer absolutely sizzles inside the magazine, which names her its Obsession of the Year. No objections here!

This might be the sexiest photo shoot she's ever done. Not that we're complaining Click to enlarge lots more Leighton Meester pictures from GQ ...

Hilary Duff has left the building. The actress has concluded her run on Gossip Girl as Olivia Burke and there are no plans for her to come back this season.

That much was kind of expected after this week's episode and the aftermath of the now-infamous threesome. Olivia doubted Dan's feelings for her and left NYU.

But here's some other couples scoop E! Online just unearthed:

• Dan and Vanessa, as foreshadowed in "The Last Days of Disco Stick," are most definitely on. They will be getting together this season.
• Ditto Nate and Serena, who will become a bona fide couple.
• Rufus and Lily will have a major problem (Serena's father).
• Chuck and Blair will be going strong.

How do we feel about all of this? Discuss!

OMG. Is Blair borrowing a page from Jenny?

That's what it looks like in the photo below? Gossip Girl star Leighton Meester looked almost unrecognizable thanks to her raccoon eyes, pale skin and red lipstick at Tuesday's American Eagle Outfitters flagship store launch in NYC.

What do you think of her eye-popping look?

Does the heavy makeup work on Leighton Meester?

Who's hotter, Ed Westwick or Sebastian Stan?

At a screening for her new movie The Private Lives Of Pippa Lee in New York, Blake Lively wore the kind of ensemble only she could get away with.

Seriously ... this is a new one, even for her. She's kind of like a delicious, decadent wedding cake with cleavage, you could say. Or you could say wow ...

Only Blake Lively can wear an outfit like this.

It's as if she's heeded the call of one of our Round Table panelists, who has been distraught by the lack of Serena cleavage for the past several episodes.

She shows a lot more than cleavage in The Private Lives Of Pippa Lee, interestingly. We haven't seen it ourselves, but there's a Blake Lively nude scene.

 “I think it’s uncomfortable, laying in strategically placed clothes taped on your body, in front of some strangers,” said Blake Lively of that part of the film.

Her co-star in it? Oscar winner Alan Arkin, 75.

“We’re all actors, we’re all professionals and we all understood what was happening. Everybody is uncomfortable with those scenes. You’re not going to be comfortable being half-naked in front of anyone. But, it was fine. It was short.”

Like Gossip Girl herself, we're lucky to receive tips from our readers sometimes. One just sent us a series of pictures taken on the set of the show today.

The cast is filming episode 13 of this season - we think that's "Jenny, Full of Grace" and scheduled to air January 11. What do the grainy photos depict?

It's unclear. But it appears to be Serena and Nate kissing behind that screen. Doesn't it? After he bared his soul last night, it wouldn't be too surprising.

Tell us what you think of this development - whether you're seeing what we're seeing, and whether you're excited about it - by commenting below!

Is there trouble ahead for Chair? It doesn't look like it. That's the good news from today's E! Online spoiler column. There's bad news for another couple, however.

One you might not expect to run into trouble so soon.

Tell us what you think of the following excerpt ...

Q: I'm a freak for Chuck and Blair on Gossip Girl, especially now that they're together! Tell me they aren't going to break up any time soon.

A: They aren't. It's actually Rufus and Lily's relationship that will be in a very bad place until the end of the season. According to sources, it all stems from that letter that Serena's father is going to send her.

And of course, it doesn't help that Bart Bass is back in the mix!

What could drive this newly-wedded couple apart? Will they make it?

Welcome to the Gossip Girl Insider Round Table!

With our Gossip Girl forum buzzing all day with fan reactions, it's the Insider's turn to discuss burning questions, funny quotes and hot moments from last night.

Gossip Girl topics from "The Last Days of Disco Stick" include classic quotes, the threesome aftermath, Lady Gaga and bad decisions by the show's blondes ...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1. What was your favorite Gossip Girl quote from the episode?

DANdy: Olivia's multi-layered quote about V: "Boxing out is one of Vanessa's favorite activities." Regarding a threesome, this is a funny, pun-laden insult. Regarding basketball, it's a compliment.

Gossip Guy: "I'm Chuck Bass. Even Europeans must know what that means."

Mister Meester: Blair was such a snot this week, even for her. She rules! Among her best lines: "I don't converse with liars or Lewinskys." "Humphrey, this isn't terrible! "I have an army to build, a school to take over, girls to blackmail."

2. Are you upset that Olivia's gone?

DANdy: Not really. Her O face never really did it for me.

Gossip Guy: No. Now every time I think of Olivia, nay Hillary Duff, I will conjure up images of Dan kissing Vanessa. Way to ruin a character I kind of liked for Dan.

Mister Meester: A little, but not too much. She's a cutie but the romance ran its course. Now we get to see Dan pine for BFF Vanessa, which is awesome ... right?
