Lisa met Gabriel in 1993, a year after her ill-fated first marriage to chef Marco Pierre White had ended.
The handsome and incredibly charming Gabriel was the perfect antidote to that difficult first marriage, and a blissfully happy Lisa put her career on hold and went to live in Chile.
But finding herself in a foreign country with a young baby Olivia was born within a year of the marriage made Lisa feel isolated, which was compounded by the fact that so much of her husband's time was spent running his farm and pursuing his polo career.
Looking back, Lisa thinks that her decision to end the marriage and return to Britain when she was pregnant with Amber was immature. Indeed the most difficult part of coming to terms with losing the father of her children was the discovery in the days following Gabriel's death that her ex-husband had not, as she had thought, ever moved on from their relationship.
"The hardest part for me was going back to the house in which I had lived with him ten years ago, and it was exactly the same. He still had all my things there, he still had the presents I had given him and my picture was everywhere."
"I realised then that he hadn't moved on and that I was the one he had loved more than anyone, and that broke my heart because I had no idea. He didn't tell me and it's too late, I can't talk to him now," she says emotionally.
