Farrah Fawcett, Ryan O'Neal

Ryan O'Neal says he is in absolute "awe" of Farrah Fawcett's courage and strength.

"In the last two years, I loved her more than I've ever loved her — ever," O'Neal told Meredith Vieira in an interview for Today. "She's so much more of a woman and powerful, courageous, fearless, all those adjectives. I look at her with awe."

In the emotional interview, O'Neal, 67, admitted he is unsure how he will fare with his longtime love no longer in his life.

"She's extraordinary. I don't know what I'll do without her, to tell you the truth," O'Neal said.

The 62-year-old Fawcett, whose anal cancer has spread to her liver, was first diagnosed in October of 2006. Fawcett believed she was winning her battle with cancer in February 2007 when she announced she was cancer-free after receiving holistic treatment in Germany that appeared to be working.

"She was so happy," O'Neal said. "It's insidious, cancer. It thinks — it lets you think you're ahead."

Vieira also spoke with Fawcett's friend, Alana Stewart, in segments that will air on the morning show on Wednesday and Thursday.

O'Neal and Stewart will participate in Farrah Fawcett's documentary, Farrah's Story, which airs Friday at 9 pm/ET on NBC.
