Yolanda Hadid's mother Ans van den Herik has died aged 78.

The 55-year-old supermodel took to Instagram in the early hours of Saturday (31.08.19) to pay tribute to her ''guardian angel'' after she passed away following a battle with cancer.

In a lengthy and touching post, she wrote: ''RIP my guardian angel Mama, Thank you for loving me the way the way that you did and for making me the woman that I am today.

''On angel wings you were taken away, but in my heart you will always stay..... I can not imagine this life without you but I pray that I will hear you whisper in the tallest trees and feel your love in the gentle breeze...

''When I miss you the most, our beautiful memories will hold you close... Our Love is eternal and you will always be with me and i will always be with you beyond the bounds of this realm

''Rest In Peace my beautiful mama, I will honor you for the rest of my days..... Until we meet again, I LOVE YOU (sic)''

Yolanda's daughter Bella remembered her grandmother on her own Instagram Stories with some photos.

She wrote: ''I wish I could hug you right now.''

Meanwhile, the 22-year-old model's older sister Gigi, 24, paid tribute herself by liking her mother's heartfelt post.

Yolanda previously opened up about her own upbringing, and revealed her other had to work hard to raise the family after her father was killed in an accident.

She said: ''I so vividly remember that winter day of the funeral when my feet were nervously dangling off the church bench as I looked at my devastated mother, brother and family.'

''My mother was incredible, both strong and loving. She learned to be an independent mom, widowed at the age of 30 and devoted her life to my brother and me.

''Strangely, she never mentioned my dad, so I cried myself to sleep at night and learned to deal with the loss of the most important person in my young life, my daddy.''
