Nicole Kidman revealed she was heartbroken over the death of her father this month and thanked well-wishers for their comforting thoughts and prayers.

"We would just like to thank everyone for their love and prayers over these past couple of weeks," the actress and her singer husband, Keith Urban, said in a joint statement posted Tuesday on Facebook.

"We are all heartbroken, but knowing we are in the hearts and thoughts of others is so comforting," they added.

They signed off: "Sending love, Nic and Keith xx."

The Australian star of this year's Grace of Monaco returned to her home of Sydney after her psychologist father, Tony Kidman, died during a vacation in Singapore on Sept. 12.

The 75-year-old was in Singapore to visit his other daughter, Antonia, and her family.

Authorities did not reveal the cause of his death.
