While speaking with ESPN's Rick Reilly after his one-man Las Vegas performance, "Mike Tyson: Undisputed Truth," the ex-boxer revealed topics he left out of the show, including the pregnancy comment, the New York Daily News reported Thursday.
"I didn't talk about getting a prison official pregnant," Tyson said. "Oh yeah. In prison, stuff happens. But she had no baby."
Tyson didn't say when he and the female prison official were together.
He served three years of a 10-year sentence for the rape conviction. The case involved an 18-year-old woman.
Tyson was released in 1995.
The former boxer also discussed his previous drug use.
"I just liked morphine," he said, "but I had to take a lot of it because it didn't stay in your system for a long time ... And I'd have my cocaine and I had my marijuana and I had my Cialis and Viagra ... ."
"That's just how I lived my life," Tyson said.
Tyson's Vegas show ran from April 13 to Wednesday.
