Sharing a snap from their wedding ceremony, which took place at a 16th century fortress in Florence, Italy, Kim wrote: “4 years down and forever to go…
“Thank you babe for giving me our family and caring so much about us.
“Thank you for inspiring me on a daily, I’m so lucky. I can’t wait for forever…Happy Anniversary.”
The couple chose to marry in Florence because it was where they conceived their daughter North, who was born just under a year prior to their big day in June 2013.
The famous spouses have since welcomed son Saint, two, and four-month-old Chicago.
