Yolanda Foster claims her ex-husband David "saved her life".
The 'Real Housewives of Beverly Hills' star has opened up about the past year, admitting she has her former spouse to thank for forcing her to go to a scan, which revealed one of her breast implants had moved.
She wrote: "After being properly diagnosed three years ago, I followed strict doctor's orders 24/7 but made very slow progress as we slowly uncovered the mystery of my failing health.
"Last June, David woke up one morning and said, 'We are not doing any more treatments until you get a full body scan.' That scan probably saved my life, as doctors found free-floating silicone under my left arm pit, under my right clavicle bone, and under my rib cage."
The 51-year-old television personality is currently on holiday with her three children Gigi, Bella and Anwar Hadid.
In her column for BravoTV.com, she added: "I'm in the snow with my children. We had a beautiful, quiet, no gifting, no stress Christmas; we cooked, ate too much, and played lots of games. Our family tradition of handwritten letters to each other is the one thing I keep close to my heart as there is no greater gift than feeling appreciated by your loved ones.
"Even though it's freezing cold, it feels good to be close to nature and the infectious energy that comes with having everyone together under one roof--keeping up is worth the fight. I want to be as present as I can be right here, right now, as I know these are precious moments as I watch my kids grow. The holidays come and go so quickly - this break from my disciplined routine is a treat."
