The 77-year-old actress reveals to The Hollywood Reporter that she once went skinny dipping with the late Michael Jackson -- as well as legendary actress Greta Garbo -- in the early 1980s. Fonda says Jackson came to stay with her for 10 days when she was filming 1982's On Golden Pond, and that her co-star, legendary actress Katharine Hepburn, initially disapproved.
"When I first asked her permission ... she was not happy," Fonda recalls. "But then the crew said, 'You don’t understand, it's Michael Jackson.'"
"She was very prickly," Fonda adds of the screen idol. "I mean, she was a snob, she was very moody, she was very judgmental."
Fonda says Jackson lived with her at her house on the New Hampshire set, and that Hepburn not only eventually accepted him, but mentored him as well.
"[Jackson] wanted to be a movie star -- he had just finished doing The Wiz," Fonda explains. "And he had a tape recorder with him, and every day I would bring him to the set, and in between scenes she would sit down in a chair and pull over a chair for him and tell him stories. ... And every story embedded a lesson."
One lesson, she shares, had to do with theater and silent film star Laurette Taylor. Fonda says Hepburn saw Taylor in The Glass Menagerie and was moved by it, but saw her 25 or 30 years later, and "the magic was gone."
"And she said to Michael, 'She wasn't hungry anymore' -- what a great thing to say to a young, rising star like Michael," Fonda now muses. "You gotta stay hungry. Don't ever phone it in. Don't ever take it for granted. You know what I mean?"
And is Fonda still "hungry" to this day?
"Oh, you have no idea," she swiftly answered back.
This, of course, isn't the first time the Grace and Frankie actress has opened up about very personal experiences. While playing a game of "Never Have I Ever" on The Ellen DeGeneres Show in May, she surprisingly revealed she's a member of the mile-high club.
"It was my fourth date with Ted Turner -- he has his own plane -- and we get on the plane and he asks, 'Are you a member of the mile-high club?'" she recalled about her third husband. "But I didn't know what he was talking about. And then I joined!"
