• Princess Diana's niece Lady Amelia Spencer got married in a custom Versace gown in South Africa.
• The gown was backless and had lace and semi-sheer detailing.

Lady Amelia Spencer got married in a Versace wedding dress that had a special nod to her late aunt Princess Diana, according to an exclusive interview with Hello Magazine.

Amelia, 30, wed her long-term partner, Greg Mallett, 33, on a mountaintop at Quoin Rock Manor House in the Winelands of Western Cape, South Africa, on March 21, the publication reported on Sunday.

Diana's niece walked down the aisle in a custom gown by Versace, one of the late royal's favorite designers, according to Hello Magazine. The backless, lace gown had long sleeves, floral and sheer detailing on the waist, Swarovski crystals, and a two-and-a-half-meter train.

She completed the look with a five-meter veil made out of fine silk tulle and Jimmy Choo shoes, the publication reports. Photos of the bride's dress were published in Hello Magazine and in an Instagram post shared on Amelia's official account.

Amelia shared a photo of herself and Mallett, who wore a tuxedo and bow tie, alongside the caption: "Forever, in this life and the next."

Diana was close friends with the late Gianni Versace and often wore his designs, according to Hello Magazine. She befriended the designer after modeling a blue Atelier Versace gown on a magazine cover in 1991, Vogue reports.

"I think she would be very proud to see me on my wedding day," Amelia said of Diana in an interview with Hello Magazine.

"I know the Versace family also absolutely love Diana, so there's a very special connection that we have," she added.

Amelia is the daughter of Diana's brother, Earl Spencer, and former model Victoria Lockwood. Her twin sister, Lady Eliza, was maid of honor and wore a pink dress that was also custom-made by Versace, Hello Magazine reports.

Amelia's father was unable to attend the wedding, therefore her younger brother Samuel Aitken walked her down the aisle, according to the publication.

Amelia was born in the UK and her family relocated to South Africa when she was a child, according to her profile on Storm Management's website. She currently works as a wedding planner in South Africa, a model in London, and an ambassador for luxury brands, her profile states.

Representatives for Lady Amelia and Versace did not immediately respond to Insider's request for comment.
