Jane Fonda made a mistake, and now she's owning up to it.
Reflecting back on her life, the Oscar winner now regrets her controversial photo op at a North Vietnamese gun site in 1972 that earned her the handle "Hanoi Jane" and calls the incident a "betrayal" of the American military and "the largest lapse of judgment that I can even imagine."
Fonda dropped the extraordinary bombshell in an interview airing Sunday with 60 Minutes correspondent Leslie Stahl that also served to plug her 600-page memoir, Jane Fonda: My Life So Far, due in stores Apr. 5.
"The image of Jane Fonda, Barbarella, Henry Fonda's daughter...sitting on an enemy aircraft gun was a betrayal," Fonda acknowledged.
The 67-year-old actress and activist, however, defended her decision to go to Hanoi and said she had no regrets about being photographed with American POWs there or making broadcasts on Radio Hanoi because she was trying to stop the war.
"There are hundreds of American delegations that had met with the POWs," she added. "Both sides were using the POWs for propaganda. It's not something that I will apologize for."
Added Fonda: "Our government was lying to us and men were dying because of it, and I felt I had to do anything that I could to expose the lies and help end the war."
That's not the only candid confession Fonda makes during the course of her 60 Minutes sitdown.
The aerobics queen also acknowledged that her first hubby, French film director Roger Vadim, pressured her into threesomes with other women.
Fonda revealed that she went along with the romps and even solicited call girls to their bed even though it was not something she felt comfortable doing.
"I know one thing, it really hurt me...and it reinforced my feeling that I wasn't good enough," she said. "I felt that, if I said no, that he would leave me, and I couldn't imagine myself without him."
The Hollywood legend said the painful experiences helped her shape her role as a prostitute in 1971's Klute , for which she won her first Best Actress Academy Award. She nabbed another for playing the wife of a Vietnam vet in 1978's Coming Home.
After her marriage to Vadim ended, Fonda next married student activist turned politician Tom Hayden and, after that union ended, billionaire mogul Ted Turner. All of her marriages ended in divorce.
She's set to make her first big-screen turn in 15 years with the May 6 release of Monster-in-Law, a comedy costarring Jennifer Lopez and Michael Vartan.
And after those grueling workouts that helped usher in the exercise craze in the '80s, the fitness guru also recently announced she'll undergo hip-replacement surgery in May or June once she's finished doing publicity for her movie.
