Nicole Kidman's father, Dr. Antony Kidman, reportedly died after falling in his hotel room in Singapore.

Kidman's publicist Wendy Day told the Daily Mail on Friday, "The family is in shock and is grieving. I think that some time and privacy is needed to deal with this shock and tragedy."

Right now, not much is known about his passing, but Singapore police told Reuters that they are currently investigating the "unnatural death."

Dr. Kidman was a clinical psychologist at the University of Technology in Sydney, Australia and he also was the Director of the Health Psychology Unit at the Royal North Shore Hospital.

One of Dr. Kidman's colleagues, Attila Brungs, released a statement to Reuters which read, "It is with great sadness that we learn of Dr. Tony Kidman’s sudden passing. During his 43 years at the University of Technology, Sydney, Tony has contributed greatly – as a colleague, as a researcher, and as a health practitioner. Tony will be missed by all at UTS. Our thoughts are with his family at this time."

Kidman was reportedly in Singapore to visit his youngest daughter Antonia.
