“Oh yeah. In prison, stuff happens. But she had no baby,” he said.
While he did not discuss when exactly the incident occurred, his longest stint behind bars was when he was convicted of raping 18-year-old beauty queen Desiree Washington in 1992.
The 45-year-old was handed a 10-year sentence, six in jail and four on probation, though he was eventually released after serving just three.
He served his sentence at the Indiana Youth Center, which later was named the North Plainfield Correctional Facility.
The hard-hitting athlete regained his WBC heavyweight title soon after being released, scoring an easy victory over champion Frank Bruno in March 1996, and added the WBA strap months later.
However, his comeback was short-lived as he was knocked out of the title by unfancied former champion Evander Holyfield in November that year.
The one-time boxing prodigy was arrested 38 times by the time he was 13, and he ended up being put in the Tryon School for Boys in Johnstown, N.Y.
Tyson is the father of eight children, and has two with current wife Kiki.
The Hangover star also discussed his former drug use, speaking about the substances he used.
“I just liked morphine, 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 and my little friends all sitting there,” he added.
