Simpson also opens up about Brown Simpson's wake and leaning over and kissing her. "It was tough, I just remember seeing her there and I still had so many feelings of ...if you're angry with a person upon their death, if you're angry with someone about whatever is going on in your life, when they die, it's not like that anger disappears," he tells Regan.
As for what he said when he leaned over to kiss Brown Simpson, the former NFL pro claims that he was told that he said "I'm sorry," but notes, "I don't know that I said anything to be honest with you."
In an outtake from the special obtained by TMZ, Regan talks about how she managed to land an interview with Simpson and why he chose to title his book, If I Did It.
Regan claims that Simpson's attorney told her flat out that Simpson was ready to confess to the murders of Brown Simpson and Goldman.
"The only condition was that he didn't want to call the book I Did It. He wanted to put an 'if' in front of it, so that he would have deniability with his children," Regan says. "He couldn't face his children and he couldn't tell them that he had done it. That was the way it was portrayed to me."
On Oct. 1, Simpson, 70, was released from prison after serving a nine-year sentence for his part in a botched hotel-room heist of sports memorabilia in Las Vegas in September 2007.
