The 52-year-old "Celebrity Apprentice" winner has canceled the remainder of his performances during the weeklong cruise that wraps up Sunday after stops in Jamaica, Grand Cayman and Mexico.
There were no other details available. An email to Norwegian Cruise Lines seeking information was not immediately returned.
