Jordan, 50, and his bride-to-be Prieto, 34, have been engaged since December, 2011 but have held off their nuptials until now.
According to the Chicago SunTimes, those on the invite list were given specific orders not to bring any cameras or cell phones, to avoid the temptation of snapping photos. They were also asked not to speak to the press or family members who may spill any details.
The precautions come several weeks after Jordan made headlines again for accusations that he had fathered a son with a Georgia-based sex instructor.
The black tie affair is scheduled to take place in Palm Beach, Florida, on April 27.
