J.K. Rowling Starts Cat Fight With "50 Shades" Author E.L. James

Description:Apparently not everyone is a fan of "50 Shades of Grey." After releasing her own "adult" book, Harry Potter author J.K. Rowling took swipes at E.L. James' "Shades" saying she never read it, but still compared it to porn. "Shades" has sold 40-million copies worldwide, beating "Harry Potter" as the fastest-selling paper back of all time.
