Exodus Tyson was taken off life support May 26, a day after she accidentally strangled herself on a piece of exercise equipment at the home of her mother, Mike Tyson's ex-girlfriend, Sol Xochitl.
E! News said Tyson made Spicer his third wife at the Las Vegas Hilton Hotel's La Bella Wedding Chapel Saturday night in a low-key ceremony with no guests in attendance.
Chapel spokesman Shawn Absher told the TV news program Tyson and Spicer seemed "very happy and very sincere."
The bride wore "an appropriate dress" and Tyson donned a suit and tie, Absher said, adding the former heavyweight champion asked that photos snapped at his wedding be kept private.
Tyson has a cameo in the big-screen, Las Vegas-set comedy "The Hangover," which was No. 1 at the U.S. box office when it opened in last weekend.
