Friends of Farrah Fawcett are opening up about the death of the Hollywood icon after she passed away on Thursday morning at the age of 62.

Actor George Hamilton -- former husband to Farrah's best friend Alana Stewart -- says of the actress, "She was the strongest woman I ever met who fought this battle for three years to the end. She never felt sorry for herself, and she was the sweetest and kindest lady and I will miss her very much."

George joined Farrah in Germany when she was receiving medical treatments.

Farrah's "Charlie's Angels" co-star and the voice of Charlie, John Forsythe, told ET, "Though I did not know her well, Farrah left an indelible mark on me and the public during her one year reign on 'Charlie's Angels.' She put up a gallant fight and I send my deepest sympathy and prayers to her family and friends."

Mike Pingel, former assistant and close friend to the actress, says of her passing, "Farrah touched my life with her smile and heart. I will never forget her soft voice, her laugh and sense of humor. She fought the toughest fight of her life and has given hope for millions who are fighting their own personal battle with cancer. I will always remember her devotion to her father, son, friends and adoring fans. I will miss making her favorite foods and especially German Chocolate cake and her favorite burnt chocolate chip cookies. I was blessed to call Farrah my friend. Farrah touched my life and I will miss her forever."

Nicole Richie also sent out a Twitter regarding the actress' death, "Rest in peace Farrah." Soleil Moon Frye also tweeted, "RIP Farrah. Your courage inspired us all."

"American Idol" judge Paula Abdul sent out a tweet that read, "What a wonderful, beautiful woman inside & out. Kind as can be, an amazing fighter who always kept hope in her heart. ... We can all learn a lot from her tremendous will to keep on fighting. God Bless You Farrah & may she finally rest in peace."

Renowned hairstylist José Eber, who worked with Farrah for over 30 years and was a personal friend, tells ET: "A golden child has been taken from this world to a better place. My life was truly blessed when Farrah and I found each other. She will remain alive in the hearts of all who loved her. Her generosity of spirit and beauty never dies. She is out of pain now and in God's arms. I am sad to lose my dear friend, her smile will remain in my heart forever."

Cancer survivor Christina Applegate reacts to the news on her Twitter, "Today please donate money to a great cancer organization for research. This damn disease has taken another. We must find a cure. Farrah R.I.P."

Farrah is survived by her 24-year-old son, Redmond, and her longtime friend and companion, Ryan O'Neal.
