I have yet to grasp why she and her sisters are famous.
I can give you three reasons her sister is famous.
Big butts, no brains.
Because her their father was an unethical disbarred lawyer who was a friend of OJ Simpson. The really outrageous thing about Robert Kardashian was that the prosecution didn't challenge his readmission to the California bar so he could be on OJ's legal team. This allowed Kardashian to claim lawyer-client privilege for the conversations he had with OJ after Nicole Simpson's murder. Robert Kardashian was not a lawyer at the time those conversations occurred, so there is no way a lawyer-client privilege should have have applied in that case. The prosecution really blew it on that point.
