Dennis Hopper, 73, who is reportedly in the final stages of prostate cancer, has filed for divorce from his wife of 14 years, Victoria Duffy. They have a daughter Galen, 6 (left with Duffy and Hopper in 2008). Citing irreconcilable differences, Hopper has asked for joint physical and legal custody of Galen. He has three other children from previous marriages. Hopper has been married five times, including a union with the Mamas & Papas singer Michelle Phillips that lasted for eight days.
