Jane Fonda is turning 80 later this year and she’s more than happy to talk about it.

Appearing on “The Ellen DeGeneres Show” Tuesday, Fonda fields ideas from DeGeneres for a “9 to 5” reunion movie with co-stars Dolly Parton and Lily Tomlin, though she doesn’t seem too taken with the idea of a retirement home as the setting.

That’s when the legendary star reveals she’s about to turn 80 and that remarkably she’s still in tip-top shape.

“If you’re 20 and you don’t know how you’re going to live past 30, then when you realize that you’re going to be 80 it’s like a miracle,” she jokes. “I don’t know how come I survived.”

“I do feel like I’m just starting out,” Fonda adds. “Isn’t that weird?”

Fonda is working a lot, she points out, including starring in “Grace and Frankie” with Tomlin. “Lily and I have promised each other that we were going to stay healthy so we could do it forever,” she says.

Then there’s Fonda’s other longtime acting relationship, with Robert Redford. She’s currently starring in her fourth film with Redford, “Our Souls at Night”, and DeGeneres asks her about a love scene in the movie she was apparently unhappy with.

“There is eventually a love scene. I mean, I was happy with it,” Fonda says. “I’m unhappy with it because it was so short.” Though she points out she’s filmed a number of love scenes with Redford over the years, saying, “I’ve been in bed with Bob a lot.”

“God, wasn’t he gorgeous,” Fonda says of Redford, remembering their film “Barefoot in the Park” and joking, “We were in bed a lot there, oh yes.”
