Not even getting stood up by Justin-Bobby or the passive-aggressive, bitter cat fights on The Hills could prepare somebody for this kind of gruesomeness.

Audrina Patridge has joined the cast of Sorority Row, a soon-to-be-filmed remake of the 1983 cult classic / horror flick The House on Sorority Row.

The aspiring actress joins previously-announced leads Briana Evigan (Step Up 2: The Streets) and Rumer Willis (The House Bunny) for the film.

Lo has brought Audrina to tears. A mysterious killer gets his/her shot next.

The film’s official plot synopsis:

“Five sorority girls inadvertently cause the murder of one of their sisters in a prank gone wrong, and agree to keep the matter to themselves and never speak of it again, so they can get on with their lives. This proves easier said than done, when after graduation a mysterious killer goes after the five of them and anyone who knows their secret.”

Sounds like this bad guy is even more evil than Spencer Pratt!
