According to one insider, "The premiere was supposed to have been on Oct. 11 in Chicago, but Paris called at the last minute and canceled, claiming she had to promote her album. The producers didn't want to have the premiere without her because she's the biggest star in the movie, which also features Simon Rex and Randy Spelling, so they rescheduled for Oct. 28."

But now Hilton has told the producers she won't likely be attending then, either.

"The movie is horrific," said our source. "It is a limited release that will likely go straight to video. Paris doesn't really want to be associated with it. Her movie career is not exactly booming, and she needs to not be seen as a flop. Also, the movie has a lot of topless women in it, and she is trying to distance herself from the whole porn thing."

A rep for Hilton said only, "She will appear at this premiere."
