Farrah Fawcett’s longtime friend, Alana Stewart, will publish a diary she kept during the late actress’ three-year battle with anal cancer, Harper Collins imprint William Morrow announced today in a press release. Fawcett, known best for her role on Charlie’s Angels, died June 25 at age 62. A portion of the proceeds from sales of My Journey with Farrah: A Story of Life, Love, and Friendship will go to The Farrah Fawcett foundation to benefit cancer research. “Farrah had originally encouraged me to write this book. It was her idea,” said Stewart in the publisher’s statement. “My hope is that people will find this book to be a heartfelt tribute to my friend of thirty years and her valiant fight against cancer.” My Journey With Farrah hits bookstores Aug. 11.
