King told guest Will Smith that she left her husband because he was cheating.
"I was married to a cheater," King told Smith, who revealed the secrets of his own happy marriage to Jada Pinkett Smith. "I went to marital counseling. I have been divorced since 1993, so I'm all healed and everything. I have worked it out. I'm not bitter. I'm OK. I'm really OK."
King's ex-husband, Connecticut Assistant Attorney General William Bumpus, did not return phone or e-mail requests from the Daily News for comment.
King told Smith that she has kept lines of communication with Bumpus open for the sake of their children who are both college-age, the Daily News report said.
"It's so important for people who have children together to get along," she said. "Regardless of how you feel about the other as a spouse, you still have these children to raise together."
