Disgraced sister of the groom gets a starring role at Lady Amelia Spencer’s wedding to Greg Mallett

Lady Amelia Spencer’s future sister-in-law is understood to have played a key role at her brother’s wedding.  

It is believed that South African model-turned-history teacher Fiona Viotti was matron of honour when her brother Greg Mallett tied the knot with his fiancée Lady Amelia, niece of Princess Diana.

Fiona made headlines in 2019 when she suddenly resigned from her teaching job at the  exclusive £16,000-per-year Bishops Diocesan College in Cape Town, after an 18-year-old student came forward to say he was in an ‘intense’ sexual relationship with her. 

Explicit videos of Fiona were shared around the all-boys college and online, and a subsequent investigation by the school concluded she had engaged in sexual conduct with five boys between 2013 and 2019.

An investigation by the SA Council for Educators was closed in 2020 after no witnesses were willing to testify. And despite plans to interview more than 40 present and former pupils, no criminal charges were brought after parents refused to allow their children to cooperate with the inquiry.

Following the scandal, it was reported that Fiona split from her husband Pavo Viotti, with sources saying she had gone on to seek ‘medical help’. 

Ahead of their wedding, Lady Amelia and Greg Mallett, both 30, kicked off the celebrations with a glamorous pool party in Cape Town over the weekend, where they hosted a welcome party for their guests at a luxury villa overlooking the ocean.

Looking suitably bridal in a pale halter neck frock, Lady Amelia posed with Greg for a photo, which he shared with his 8,400 followers.

He captioned the image: ‘You’ll never not make me laugh. And I will never stop looking at you in awe.’

The groom then finished off his loving post with a single red love heart emoji and tagged Amelia – who then re-shared it with her 48,400 followers.

Wedding guest Jacinta Spencer – who is a makeup artist friend and not a direct relation – also posted a photo of Lady Amelia posing on the terrace as the sun set behind her.

She wrote: ‘The most beautiful pre-wedding reception for you. I love you with all my heart.’      

While it is understood that Fiona played pivotal role in the celebrations, there was one notable absence from the guest list.

Amelia’s father Charles Spencer, who did not attend his eldest daughter Lady Kitty’s wedding to retail millionaire Michael Lewis in July 2021, is believed to have also missed this one.

When Lady Kitty –  who is 32 years younger than her husband – tied the knot, she was walked down the aisle by her brother Louis Spencer, Viscount Althorp, 29, and half brother Samuel Aitken, whose father is businessman Jonathan Aitken. 

A source told MailOnline at the time: ‘Kitty and Charles were very close when she was growing up, but their relationship has cooled and been more distant since his marriage to his third wife Karen in 2011.

‘Charles recently suffered an injury and perhaps that will be the reason for him not travelling, but it is just easier for everyone that he is not there.’

While Lady Amelia kicked off the celebrations in South Africa, Charles was seemingly in the UK, tweeting a video of a group of lambs at his Althorp Estate home.  

Posting on Twitter yesterday, Charles wrote: ‘Lambs, recently born, settling in to life in the Park at ⁦Althorp House.’

Lady Amelia got engaged to long-term boyfriend Greg in 2020, after a romantic proposal in South Africa.

The society beauty, who is the cousin of Princes William and Harry, met her real estate beau while they were both studying at the University of Cape Town.

The couple were together for 11 years before Greg popped the question at the exclusive Clouds Wine & Guest Estate in Stellenbosch.
