'Gossip Girl' series finale spoilers: Taylor Momsen, Connor Paolo, Katie Cassidy and more to return

"Gossip Girl" is currently filming its series finale in NYC, and all signs point to Chuck and Blair getting married in a quickie ceremony performed by her diminutive stepfather, Cyrus (Wallace Shawn, who will guest star in the finale).

The cast gathered at the Bethesda Terrace in Central Park to shoot the wedding scene, which is considerably smaller than Blair's royal wedding last season. Also, this time, she's wearing blue. Attended only by her closest friends (and Georgina), the wedding appears to be interrupted by police officers.

Of course, this is "Gossip Girl" -- and there's always the chance that the wedding is a dream sequence. (Mostly because Georgina is there. Come on now.) What we can confirm for sure is that the finale will feature plenty of familiar faces. Connor Paolo took a little time off from his "Revenge" filming duties to fly back to NYC and reprise his role as Eric van der Woodsen, and he's joined by the rebellious Jenny Humphrey (Taylor Momsen) as well.

CW mainstay Katie Cassidy will also return. Last week, she flew into New York to revisit the scheming Juliet Sharp, taking some time away from her new gig on "Arrow" before rejoining her "Arrow" castmates at New York Comic Con this weekend.
