"I was in a relationship for a couple of years. I was in love with him and people I think do that sometimes. And I never thought that it would get out and that I'd be hurt like that. ... It was one of the hardest things that's ever happened in my life and humiliating, but because of it I became a better person," she said.
This is the year that Oprah Winfrey turned 50. She has continued to inspire young and old alike, and believes that she was born at the right time to do great things.
She shares with Walters the personal choices she has made, especially not becoming a mother. "I do feel in many ways that the world's children, the community's children, are my children," she said. "I feel I can be a voice for children who don't or are not allowed to speak for themselves."
Real estate mogul Donald Trump was already famous when his reality show "The Apprentice" premiered earlier this year. Now he's hotter than ever, and joining him in his interview with Walters is his bride-to-be, Melania Knauss, who extols Trump's modesty: "He's a great man. He should live forever."
Has Trump ever heard the two-word tag line that leaves "Apprentice" contestants crushed? "I am not bragging. My father was a very tough guy. And I did a great job for him. And he knew it. And he totally relied on me. And he knew it. And he knew how good I was. I had done a really good job. So no, I have never been fired," he said.
On Nov. 30, Ken Jennings was dethroned as the reigning king of "Jeopardy!" But he had a record-breaking 75 appearances on the show, winning more than $2.5 million.
Jennings told Walters there's no real way to cram for "Jeopardy!" Although, as a teetotaler, he admits he had his wife quiz him on types of cocktails.
"I'm not someone who sits at home and reads almanacs," he said. "I think I just tend to be curious about the world around me and when I hear something I don't know about for the first time, it just sort of fascinates me and makes me want to learn more."
