Tinsley Mortimer has landed herself a cameo on Gossip Girl. They are currently out east filming for the fall and were recently shooting a scene with all the cast members dressed in white. Were they perhaps going to Diddy's annual white party? Hopefully we'll be able to score more of the scoop this afternoon at the Golf Tournament in West Hampton where the cast members are supposedly going to.
