Ryan O'Neal on bed-ridden Farrah Fawcett: "I won't know this world without her"

Farrah Fawcett Ryan O'Neal

tells People magazine in an exclusive interview in the current issue.

On Thursday night, "Access Hollywood" reported that the actress' 91-year-old father is flying in from Texas to be at her bedside. Cancer specialists from Germany are flying in as well.

O'Neal, who said Fawcett is down to a few words now, has also lost her famous golden tresses.

"She stays in bed now," O'Neal said. "The doctors see that she is comfortable. Farrah is on IVs, but some of that is for nourishment. The treatment has pretty much ended."

O'Neal revealed for the first time how the anal cancer Fawcett has fought for more than two years spread long ago to other parts of her body, including her liver.

"It's a love story. I just don't know how to play this one," said the actor who played the husband of terminally ill

Ali McGraw

in "Love Story."

"I won't know this world without her. Cancer is an insidious enemy."

Fawcett, 62, will tell the story of her illness in her own words in "Farrah's Story," a two-hour NBC documentary airing May 15. Longtime friend

Alana Stewart

helped shoot the documentary.

"It was never meant to be a documentary," says Stewart, 63. "Farrah just took her little hand-held camera to the doctor one day." It was the day, as it turned out, that Fawcett learned from her doctors the cancer she thought she had licked had returned.

O'Neal told People that Fawcett now spends her days at home, often asleep, and receiving visits from a few friends, including fellow Charlie's Angels stars

Jaclyn Smith Kate Jackson


"The hair is gone," says O'Neal. "Her famous hair. I have it at home. She didn't care. I rub her head. It's kind of fun, actually, this great, tiny little head. How she carried all that hair I'll never know. She doesn't have a vanity about it."
