Just when I thought I couldn't get more grossed out by sleazy Paris Hilton, I find this article about how she had sex with Mary-Kate Olsen's former boyfriend Stavros Niarchos in a porta-potty.According to the story, the new couple spent the evening "kissing and groping" at a Hollywood party, then went into one of the stinky portable pots to have sex. Couldn't the heiress spring for a hotel room? I'm sure she still has some pull at the Hilton.And as for those claims she didn't know Tom Sizemore? You know -- the overweight, unattractive drug addict who has a prosthetic penis and beats women. Well, here's a photo of them -- together -- at his house! What do you say now, Paris?That girl needs to be hosed down. Disinfected. Her doctor needs to just tie her down and administer the biggest dose of antibiotics ever. Dirty, dirty girl.
