Farrah Fawcett: Jaclyn Smith, Fellow 'Charlie's Angel,' Pays Tribute

June 25, 2009— -- Actress Farrah Fawcett, who lost her battle to cancer Thursday at the age of 62, shot to stardom as one of "Charlie's Angels" in the 1970s hit television show, becoming a cultural icon.

Friend and fellow angel Jaclyn Smith opened up about Fawcett's struggle for her life, as part of a special edition of "20/20" to air TONIGHT at 10 p.m.

"She had an unrelentless capacity to fight this disease," Smith told Walters.

Smith and Fawcett, along with Kate Jackson, played the three undercover, underclothed crime fighters on the 1976 hit "Charlie's Angels."

"What is it? Is it the hair? Is it the smile? Is it the body? It's just the whole package," Smith told Barbara Walters on Fawcett's stellar looks. "Her hair. I mean, I've said many times that it could have its own phone line. It had a life of its own, and I think that iconic style will be recreated for generations to come."

"I think she was truly the girl next door. ... although I didn't live next door to a girl like Farrah," she said.

The "Angels'" relationship was more than that of ordinary co-stars -- sharing their private lives with one another and, coincidentally, the bond of cancer.

"Kate experienced breast cancer, I experienced breast cancer, and then Farrah, you know, anal cancer. So, Farrah in her humor said, what was it, the water we were drinking?" Smith told Walters. "And, you know ... I mean, she, she maintained her humor, which is hard to do in the face of cancer."

After only one year on "Charlie's Angels," Fawcett walked away from the show at the height of her fame to explore a career in film -- a move, which Smith says Fawcett never thought was a mistake.

"When Farrah makes up her mind to do something, it's well thought out, it's well ordered and planned, and it's right for her," Smith told Walters. "I was sad because it was not an actress leaving, it was my friend."
