Ryan O'Neal says he plans to marry Farrah Fawcett, who is fighting cancer.
The 68-year-old actor says in an interview with Barbara Walters for ABC's "20/20" that he asked his longtime companion to marry him and "she's agreed." O'Neal says they will tie the knot "as soon as she can say yes."
Walters' interview with O'Neal airs Friday.
Fawcett was diagnosed in 2006 with anal cancer that has spread to her liver. The "Charlie's Angels" star and O'Neal have a 24-year-old son, Redmond.
O'Neal says the 62-year-old actress is "fighting for her life," but despite her declining health, they will "absolutely" get married.
Farrah and Ryan first began dating in 1979, according to People magazine.
