Kim Kardashian and Kanye West are set to tie the knot at Florence's imposing 16th Century Belvedere Fort on May 24, according to a spokeswoman at the local mayor's office.
The couple, known as "Kimye", rented the fort next to Florence's famed Boboli Gardens for €300,000 (£245,000) and a Protestant minister will conduct the wedding ceremony, Elisa Di Lupo added.
The 36-year-old rapper proposed to the reality star businesswoman on her 33rd birthday in October 2013, renting out San Francisco's AT&T Park for the occasion.
This will be West's first marriage and the third trip down the aisle for Kardashian.
Neither the Kardashian camp nor West have confirmed the report.
