If you think moguls don’t have time for sex, just ask Jane Fonda. “I know people think that people that are that powerful and busy don’t have time,” Fonda said in an interview with “Women’s Media Center Live” host Robin Morgan that aired yesterday. “There was a time when I thought that was true, and then I met Ted Turner.” Fonda added of her ex, “When [he] was winning the America’s Cup and building CNN and building his philanthropic empire, he was also sleeping with more women than I think he could count.” But Fonda wasn’t finished: “There are others . . . Warren Beatty. People who are very, very, very busy and manage to slip ’em in, one after another.” She even imagined who her own high-powered character, Leona Lansing, on Aaron Sorkin’s “The Newsroom,” has bedded. “I don’t think Leona is that promiscuous, but . . . I think she slept with Charlie Rose . . . I think she slept with Warren Buffett. She’s slept with a lot of presidents. She’s slept with John Kerry. Gary Hart tried to sleep with her, and she [said], ‘Ewwww!’ ”
