Now that Cashmere Mafia is on the killing line, its rival show Lipstick Jungle is getting ready for a big debut... at Mercedes-Benz Fashion Week. The show, developed by Candace Bushnell after her former SATC partner, Darren Starr, struck out on his own, will premiere on February 7, right in the middle of New York's runway jams. And we hear the show's PR team is taking hard advantage of the paparazzi swarming The Tents: On January 31, the Lipstick Jungle crew (including Brooke Shields... actually, she's the only real famous person involved...) will hit Saks Fifth Avenue for a launch party - "coincidentally" timed a week before their show airs, giving US Weekly exactly seven days to harness those photos for a good cause. We hear Ms. Shields is also confirmed for the Michael Kors show, and that producers are scrambling to arrange good photo opportunities for the other cast members, to make them seem as fashionable as possible. That means Kim Raver could show up at Nanette Lepore or Temperley, while we hope Lindsay Price arrives at Cynthia Rowley - after all, her character, Victory Ford, is based on Ms. Rowley herself!
