Mischa Barton was scheduled last night to host a party at CatHouse, a new Vegas club in the Luxor Hotel and Casino. Immediately after her arrest, the club changed its mind about using Hollywood’s newest DUI scandal to promote, well, drinking. Said the club in an official statement:

“Because of the media attention currently surrounding Mischa Barton, CatHouse has decided it is best for all parties involved that Mischa does not appear at tonight’s grand opening. Mischa will not be replaced as host, however VIP guests confirmed to celebrate the highly anticipated ‘loungerie’ opening include Adrien Brody, Jaime King, Jordana Brewster, Michelle Trachtenburg and Jack Osbourne, among others.”

But according to a PR guy for CatHouse, it seems now they’ve changed their mind:

“Mischa did not show up last night as expected,” the rep said. “She still has to honor her contract, and what happens next remains to be seen.”

To me, it sounds like she’s fulfilled her obligations. At least I know I never would have heard of CatHouse had Mischa not been arrested, and what club doesn’t want to be associated with irresponsible drinking and drug use?
