Taking to Instagram earlier this month, she shared a clip of a new song she'd written in his memory. In the caption, she wrote: "Dearest Marc - I loved you more than words can say and I still love you and always will. My beautiful soul connection… what we went through no one will understand or comprehend but by writing this song for you… we did good baby - we did good."

She added: 'I can only thank you so so much for being so kind when I needed love and god you did. You're a total Angel – that stays forever in my heart – gives me so much pain but the love you gave me is worth every single moment of heartbreak and you made me stronger than I ever thought possible. Dear Marc I love you."

Under the post, she revealed he had died as the result of a "massive stroke", leaving her followers stunned. One of the followers who appeared to have known her wrote: "You looked so happy together when I last saw you and I've been aware of what's going on. What a rollercoaster."

Another said: "He sounds like he was a great person. Remember the happier times and be blessed that you meant so much to one another."

Kirsty, who was born in Staffordshire, retired from the public eye in 2021 after the breakdown of her marriage with the billionaire.

In July 2023, she appeared to be coming out of the shadows when she hosted a joint birthday party with Marc in Sardinia, introducing him to the world.

During the event, she sang to him, with guests and friends describing their relationship as a "true romance", reports the MailOnline.

A friend said at the time: "She is in a better place – close friends, a new younger man, and a bulging bank balance."

At the time of her split from Ernesto, who is the father of three of her children, she was given the huge sum, a £52million Lake Geneva pad, and an £8million chalet in the Swiss Alps.

The couple were previously ranked 14th on the Sunday Times Rich List for their £9.2billion fortune.
