1970s "It Girl" and Charlie's Angel's starlet Farrah Fawcett died of anal cancer today at age 62. "After a long and brave battle with cancer, our beloved Farrah has passed away. Although this is an extremely difficult time for her family and friends, we take comfort in the beautiful times that we shared with Farrah over the years and the knowledge that her life brought joy to so many people around the world," O'Neal said in a statement released by Fawcett's publicist.First diagnosed with anal cancer in 2006 and declared cancer-free in 2007, Fawcett sought out the best treatment available from specialists from UCLA to Germany, but the cancer returned a few months later and spread to her liver.Just over a month before her death Fawcett shared an extremely intimate and personal look at her battle with cancer in the TV documentary Farrah's Story, which aired on NBC in May. Fawcett filmed much of the footage herself with a hand-held camera, along with help from her long-time partner Ryan O'Neal and close friend Alana Stewart. According to news reports, an NBC spokeswoman confirmed that the network has plans to air a follow-up to the documentary, which attracted almost 9 million viewers.In the last days of Fawcett's life, O'Neal and others close to her sat down for an exclusive interview with Barbara Walters, which is scheduled to air on ABC's 20/20 at 10 p.m. (EDT) tonight.
