'At 13, we started to become more aware of ourselves - Nikki Lund

Speaking to Heat magazine, Kim's childhood best friend Nikki Lund explained just how far back her negative feelings go. 'At 13, we started to become more aware of ourselves. We began wearing make-up and started dieting,' the fashion designer said, speaking of her days growing up with the Keeping Up With The Kardashians star. She explained: 'It was mostly the Atkins and the South Beach Diet. We did the Cabbage Soup Diet and we'd be there boiling great big vats of cabbage. We were like, "Yes, we're going to be thin."' 'Kim was always saying her nose wasn't perfect. I thought she was nuts. Every girl has something they don't like,' Nikki added to the magazine.
