The reality TV star shared several intimate photos from the couple's 2014 wedding day in Florence, Italy, on her Instagram page as she paid tribute to the U.S. rapper.
"5 years ago today I married my best friend," Kim captioned the post, which featured several photos of the pair kissing under the Tuscan sun.
The mother of four, who welcomed her newborn son Psalm earlier this month, also took the opportunity to release a new beauty range, entitled the Mrs West Collection.
Part of her KKWBEAUTY range, the new products are inspired by the look Kim's make-up artist Mario Dedivanovic created for her on her wedding day and the packaging features pictures from Kim and Kayne's special day, which took place at Fort Di Belvedere in the mountains just outside of Florence.
Kim was previously married twice before tying the knot with the "Gold Digger" hitmaker.
