That's the indication from the first Gossip Girl trailer of the sixth and final season that surfaced on the web on Friday. Mostly consisting of old footage -- and old haircuts (looking at you Dan Humphrey) -- the last seconds of the minute-long teaser will whet "Chair" fans until Monday, Oct. 8, when the CW drama kicks off its farewell episodes.

In a blink-and-you'll-miss-it moment, the trailer also features a scene with Serena (Blake Lively) and new love interest, entrepreneur Steven Spence (Barry Watson), raising a toast at a wedding. Question becomes: Is the wedding theirs?

The biggest swoon-worthy moment comes at the tail-end, with Blair declaring to Chuck: "I'm all in." Chuck's response is just as memorable: "My bet's on us."
