The Gossip Girl cast were sharing some personal photos over the weekend as they filmed the final episode of the show. They were filming the end of the sixth series and made sure they went out with a bang (and some cake). Blake Lively, Chace Crawford, Leighton Meester and Ed Westwick have become household names in the last few years since they first appeared on our screens in 2007. The photos show the actors having a cake fight as they partied together, but will there be such a happy ending for their onscreen personas too? Click through to see photos of the cast.
