Paparazzi camping outside the home of Tiger Woods‘ alleged mistress No. 1, Rachel Uchitel, on West 14th Street got a bonus Thursday night when the Cinema Society hosted an after-party for a screening of “The Young Victoria” starring Emily Blunt at the Norwood Club — which is right next door to Uchitel’s home. “All these photographers were outside the club waiting for Rachel to come home, although the celebs at the party thought they were there for them,” laughs a spy. Revelers including Martha Stewart, Martin Scorsese, Lionel Richie, Chris Noth — who was praising Blunt’s performance — Michael Stipe, Rachel Hunter and Blunt herself came and went. Alas, Uchitel never showed up. Earlier in the evening, one inebriated moviegoer slipped into the screening at the Regal Union Square and moaned through a good part of the film before he was thrown out by security.
