We always knew celebrities demanded a fee for their appearance at particular events, including fashion week.  Although part of us wanted to believe they were there for their love of fashion, the not-so-naive side of us knew there was a cash transaction taking place.   Fashionista did some digging and discovered just how much certain celebrities are paid to sit front row.  The priciest celeb is Rihanna who commands $100,000 or more to sit front row, with Beyonce and the Olsen twins coming in second and third place with a pricetag of $80,000 each.  The most surprising is how cheap Jennifer Lopez is now ($30,000)  compared with 2005 ($80,000) and the fact that people actually pay Kim Kardashian to attend their show (between $35,000 and $50,000).  Check out the round up of what the A, B and C-list celebs are paid - the numbers will frighten you!
