"I'm in shock and I have to go to my family," the statement said. "But this award is for her. She shaped me, she guided me and she made me."

In a 2018 birthday tribute, Kidman said her mom "loved me, guided me and taught me and I am so blessed to have you," and she told People last year that her mother is still "so involved in what I wear."
