If you thought Serena van der Woodsen (Blake Lively) was a bad girl, wait until you see the new and improved Lily.
In Monday's episode, "Valley Girls," we learn how Lily (Brittany Snow) became a good girl gone bad.

Except when it leads to bar fights, which you can see in the full promo below.
Are you excited for the Gossip Girl spinoff, or is the franchise split a bad decision?
