The title of the 121st and final episode of Gossip Girl has been revealed on Tumblr.

When Season 6 concludes with its 10th installment December 10, it will be called ...

"New York, I Love You XOXO."

Appropriate, no?

This call sheet (and the person who posted it) first spilled the beans. Stephanie Savage and Mark Piznarski, who wrote and directed the Gossip Girl Season 6 premiere, respectively, are slated to helm the finale.

Among the rumors surrounding this much-awaited, last-ever Gossip Girl episode:

• Just who is Gossip Girl and will she (he?) be revealed?
• Will Dan and Serena get back together?
• Do Chuck and Blair have a kid?
• Do they get married?
• Will it be satisfying?

UPDATE: It has been confirmed: Katie Cassidy was spotted on set and WILL appear on the final episode!
