Elisa Di Lupo, a representative from the Florentine mayor's office, told The Guardian that the couple had spent €300,000 ($411,000) on a 16th-century fortress built by the famed Medici family.
"I give you scarce information. That they are marrying at the Belvedere fort is true," Di Lupo said. "The fort is being used for a private event for €300,000. The municipality does not know the details of this wedding."

"To tell you the truth, I already came to the banks of the Arno [river] with Kim last year, just the two of us, incognito," he said. "I think that our daughter North was conceived here among the Renaissance masterpieces."
The wedding is expected to take place May 24.
