Note to set-crashers: "Gossip Girl," according to no parking signs, is shooting off Madison Square Park tomorrow, circa E. 25th Street or so, so you can go see the shallow for yourself. The T.V. show, which debuts next week and is about private school hissy fits between power-hungry bitches and date rapists and Upper East Side youngster alcohol consumption and a tawdry New York semi-blog, is getting a ton of advance, including in today's Times, even though it's on CW, one of those channels we don't really associate with a number. I've seen the pilot. It gives me that terrible trashy super-eww end times feeling. This means that it will be an incredible success.
