Farrah Fawcett is still "fighting for her life," Ryan O'Neal tells Barbara Walters.

But he’s asked his longtime love to marry him, and she's said yes.

"I used to ask her to marry me all the time," O'Neal said in the interview set to air Friday on "20/20." "But … it just got to be a joke, you know. We just joked about it."

But with Fawcett, 62, losing ground in her battle with anal cancer, he tells Walters that he's asked again. "I promise you, we will," says O'Neal. "Absolutely."

O'Neal might dress for the wedding "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."

God love him for keeping her spirits up and being there for her.
