“I HAVE to admit that my love life is suffering from travel fatigue, since my hectic schedule leaves little time for romance,” Jane Fonda, 70, confided to writer Gregory Speck after last week’s AFI Hollywood tribute to Warren Beatty, in whose arms she made her first screen test in 1957. “At the time I suspected thatWarren might be gay, because he was so cute and had so many unusual, intellectual friends,” Fonda told Speck. “Well, how wrong can you be? He became legendary as a great lover, so I missed out on a good thing back then, but at least I am lucky enough to have found his counterpart today in Lynden Gillis.” She and Gillis, 76, who looks like the twin brother of her late father Henry Fonda, just signed another oneyear lease at their Manhattan love pad. “I worry about rarely being there with Lynden, since a good lover and friend is so hard to come by, and you don’t want to lose him by default,” Fonda said. “When you’re too busy for love, you’re too busy, period.”
