The West Wing actress, 62, has four broken marriage behind her, with WALTER CHANNING (63-67), PAUL SCHMIDT (70-76), DAVID DEBIN (76-80) and DAVID RAWLE (80-88). Channing insists she is happy now living with her long-term partner, cinematographer DANIEL GILLHAM, whom she has been dating since 1990, she is more focused on enjoying the relationship as it is, rather then making it formal. She tells Now, "I think you can be funny about divorce. You have to. No one gets married expecting to get divorced. "But there are a lot of people who've lived with lots of different people because that's the modern world, whether we like it or not. "I've been with Daniel for 16 years. That's a huge achievement in Hollywood. "Marrying again would feel silly."
