Penn Badgley, Leighton Meester Penn Badgley, Leighton Meester

While Gossip Girl fans may be torn between who they want Blair to be with, Leighton Meester is not.

"The one relationship I'd love to play out is Blair and Dan," she told at the show's 100th episode party Saturday night. Penn Badgley (Dan) said: "I like the Blair [story line] because it's the most exciting for Dan as a person."

Although it was a surprise to see the Queen Bee and Lonely Boy, who often butted heads, start to like each other, executive producer Josh Safran said the pairing has been likely to happen since the beginning.

"I wrote the first scene with them together in Season 1 ... and we knew at that moment there was something there," he said.

But Blair and Dan getting together has a few major hitches, namely Blair's impending wedding to Prince Louis — and a baby on the way. On Monday's episode (8/7c, CW) Blair continues preparing for the big day with her bridal shower. And producers said a wedding will happen (or at least partly) when the 100th episode airs Jan. 30.

"She does walk down the aisle," said Margaret Colin, who plays Blair's mom. Added Blake Lively: "We shot a big dance sequence." So, while it seems there's a ceremony and a reception, Safran said it could all a dream.

While an enduring story line since the first season has been the Blair-and-Chuck relationship, Meester adds that she's OK with their current status.

"Her and Chuck have had ups and downs and as much as everyone loves them together, I think them having time apart has actually helped them grow," she said.

But, "Chair" fans, don't be alarmed yet. Executive producer Stephanie Savage told us: "We have some amazing Chuck-and-Blair scenes coming up in the next couple of episodes.. The Chuck-and-Blair relationship is really fun and something that wasn't in the books, but came out of Leighton and Ed [Westwick]'s chemistry."

Whether you want Blair to be with Chuck or Dan (does anyone want her with the Prince?), creator Josh Schwartz has a solution. "There's only one way to satisfy all those people," he said. "Threesome."
