Though Farrah Fawcett is "fighting for her life," Ryan O'Neal tells Barbara Walters, "I've asked her to marry me, again, and she's agreed," ABC News
"We will, as soon as she can, say yes," O'Neal, 68, says about his companion since 1980. "Maybe we can just nod her head," he said, with a laugh.
"I used to ask her to marry me all the time," O'Neal said for the interview to air Friday on 20/20
. "But ... it just got to be a joke, you know. We just joked about it."
But now with Fawcett, 62, deteriorating from cancer, "I promise you, we will," says O'Neal. "Absolutely."
Regarding dress for the ceremony, a still-jocular O'Neal plans to look "like a gigolo. You know? And a little thin mustache and slicked-back hair. I don't know. We have fun, we tease about that."
