Gossip Girl, which premieres its fifth season September 26, will reach 100 episodes in January.

The show is pulling out “all the stops” for the big milestone, too, according to Joshua Safran.

“We want to honor the [fact] that it’s the 100th episode,” said the CW show's co-executive producer. “We know that we are very lucky to be coming by it, and we’re going to respect that. So we definitely want to make it feel like it is a special event. Let’s put it this way - it’s not going to be a clip show.”

So what event will take place when Gossip Girl crosses the century mark?

We know from the official synopsis that when Season 5 commences, Blair is in full wedding planning mode, while Chuck is in L.A. (see season premiere promo from earlier). For now, they're apart - literally and otherwise.

But my midseason? That would be a workable time frame for a glamourous royal wedding to be scheduled ... and for Chuck to try to prevent the bride-to-be from becoming Princess of Monaco at the last minute.

That's just our theory. What about yours?
