Spice Girls singer Mel B has tied the nuptial knot with hairstylist Rory McPhee at The Crypt of St. Paul's Cathedral in London on Saturday.

As per images and video of the wedding ceremony that have now gone viral online, Mel B could be seen wearing ivory custom gown from Josephine Scott that had a stunning neckline covered in pearls, media reports said.

“Mel was a dream to work with, bringing her own sense of style to the occasion,” Caroline Black, the owner of Evelie Bridal Boutiques in London, who helped the musician pick out her wedding attire, told People.

A star-studded ceremony was also held at the Shangri-La Hotel inside The Shard, the UK.

Among the celebrity guests in attendance were "Baby Spice" Emma Bunton, plus Cara Delevingne, Katherine Ryan and Daisy Lowe, reported People.

Sharing an adorable image of their marriage on Instagram, Mel B wrote: "05.07.25."

According to reports, Mel B's bridesmaids were her daughters.

Mel B got the permission to marry in St. Paul's Cathedral, the venue which also hosted the marriage of Princess Diana and Prince Charles, since she received the distinction of being the  Member of the Order of the British Empire (MBE) from Prince William in 2022 for her work bringing awareness to domestic violence issues.

“It’s a big deal because when you get married there — not many people are allowed to get married there. You have to be kind of special,” Mel B shared of the iconic church on the May 14 episode of The Tonight Show Starring Jimmy Fallon, as quoted by People.
