Cancer-stricken Farrah Fawcett, 62, who is fighting for her life, has finally agreed to marry longtime boyfriend Ryan O'Neal, 68. "I've asked her to marry me, again, and she's agreed," O'Neal told 20/20 Monday. "We will, as soon as she can, say yes. I used to ask her to marry me all the time. It just got to be a joke, you know. We just joked about it." Fawcett, as one of the original cast of Charlie's Angels, was the iconic 70s pinup but has recently devoted herself to fighting anal cancer and documenting her struggle with a recent documentary.
