Everybody Thought We Were Crazy: Dennis Hopper, Brooke Hayward, and 1960s Los Angeles by Mark Rozzo:
The Newport wedding was the third for Leland. He had already been married twice, to the same woman, a Texas debutante named Inez Gibbs, known as Lola; the first of those was an elopement when he was nineteen. In order to marry Maggie, he had broken off an affair with another of his clients, Katharine Hepburn. Or perhaps he hadn’t. When the incensed Hepburn learned of the marriage, she sent a telegram to the bride: “Dear Maggie—You have just married the most wonderful man in the world.” The recipient set fire to the cable as Leland watched. “He loved it,” Brooke said. “He told us that story all the time.” Brooke believed that her father continued to oscillate between the two headstrong actresses in defiance of his wedding vows. She recalled once finding herself on an elevator with Hepburn when a mutual acquaintance introduced them. “You are Maggie and Leland’s daughter?” Hepburn asked, sizing the girl up with mock horror. “I remember thinking, ‘This is a nightmare.’
By the time of the wedding in Newport, Maggie was pregnant.
