This is just devastating news for the Kidman family.

Nicole and Antonia Kidman’s father, Dr Antony Kidman, has reportedly died in tragic circumstances.

Dr Kidman —  a respected psychologist and Director of the Health Psychology Unit at Sydney’s Royal North Shore Hospital — was visiting his younger daughter Antonia in Singapore. It’s believed that he fell and died there.

Obviously, he was loved very much by both his daughters and this is a profoundly tragic incident. Here’s a beautiful moment between him and Nicole Kidman on the red carpet.

Antonia Kidman, 44, moved to Singapore in 2010 with her partner, Craig Marran. She has six children – four by her first husband, Angus Hawley, and two with Marran. Nicole Kidman, 47, lives in Nashville with her husband, Australian country singer Keith Urban, and their two small children, Sunday Rose and Faith. Nicole has two children, Isabella and Connor, from her marriage with Tom Cruise.

Dr Kidman was given an Order of Australia medal in 2005 for his services to health and medicine. He will be remembered for his contribution to breast cancer research, clinical psychology and the psychological impact of living with cancer.

He is survived by his wife of 50 years, Janelle Kidman. In January, the whole family were together in Sydney to celebrate their 50th anniversary.

Our thoughts are with Dr Kidman’s wife, two daughters, and ten grandchildren.
