The 52-year-old is mum to models Gigi and Bella, and Anwar - her three kids from her marriage to real estate developer Mohamed Hadid.

She became Yolanda Foster when she wed music producer David Foster in 2011, but now she's planning to return to her former name after splitting from the hitmaker last year (Nov15) after four years of marriage.

"I talked about it with my kids," she said during an appearance on Watch What Happens Live! on Tuesday (16Feb16). "I never dropped the name Hadid because I had three children by that last name and I asked the kids, 'Should I go back to (maiden name) van den Herik?' and they said, 'No, you're our mommy and we have the same last name'."

Despite their impending divorce, Yolanda, a Real Housewives of Beverly Hills favourite, has thanked her estranged husband for supporting her through her difficult battle with Lyme Disease after rumours surfaced he had been questioning her health struggles, which were diagnosed in 2012.

"Only those who have experienced an invisible illness can identify with my journey," she recently wrote on her blog for "Losing my brain function and the ability to participate in life made me lose my identity. I had no choice but to buckle down, surrender, and connect to the deepest part of my soul. Only in solitude could I hear the little bit of my spirit that was still alive and willing to fight..."

"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," she continued.

Yolanda then recalled David insisting on a full body scan in June (15), and she now believes that "probably saved my life"

"Doctors found free-floating silicone (from a leaking breast implant) under my left arm pit, under my right clavicle bone, and under my rib cage," she added.

"None of these findings changed my late stage Lyme disease diagnosis, but it was a good explanation of why three years of hard work had not paid off yet. It was a big breakthrough in my case at a time that I was just existing. At that point I honestly was not sure how and if I was going to pull through."
