The Hollywood Girl Feuds are still flourishing. At the Chateau Marmont party hosted by Penelope Cruz, Mischa Barton and Rachel Zoe were having a good time - but with one eye on the door. They did NOT want to run into Nicole Richie so they had planned to make a quick escape if when and if she arrived. They also hoped to avoid Paris Hilton so they asked people to notify them if either turned up. They had their escape route carefully planned so they could leave quickly without any fuss. (The Olsen twins weren't about to let their dislike of Paris Hilton ruin THEIR good time - they just pretend she doesn't exist.) Rachel and Mischa wasted their energy - their arch enemies didn't turn up.
