Proving again that it takes trash to know trash, Paris Hilton has lashed out at the MTV reality series The Hills.

During an appearance at the FiFi Awards this week, Paris said her boyfriend Doug Reinhardt wouldn’t be back on the show, saying “The show is, like, so lame and fake. He doesn’t even want to be a part of it.” Doug was featured several times on The Hills during 2008 as Lauren Conrad’s sex buddy.

Hills regular Stephanie Pratt isn’t taking Paris’ attack lying down though, and has called on Paris to apologize. “Doug’s not even on the show, so I don’t even understand that,” Pratt said. “And in real life he is friends with those boys, so it’s not fake. I would never call her show dumb, so I think she should apologize.”

Doug isn’t exactly heading for the high road when it comes to future television appearances: he might not be returning to The Hills, but he has landed role on reality show Paris Hilton’s My New BFF season 2.
