My interpretation of the article is that she's having a reality show like The Bachelor, but to find a best friend instead of a boyfriend and she is equating the house they will all be living in to being in a sorority, not that she will actually be living in a sorority house.

This is what I understand too. SHE implied it would be a "sorority-like" experience (showing how much she misunderstands what that is). I can't imagine ANY group (local or not) opening themselves up for the shame and ridicule that would undoubtedly follow their allowing Paris to "be" one of them.

Yes,it is jut what Paris equates as a sorority. My understanding is that it is going to be just a random group of girls living together in hopes of breeding drama and so called entertainment.
