Nicole Kidman‘s daughters didn’t beat around the bush when they saw her movie makeover forDestroyer.

When her kids with husbandKeith Urban—Faith Margaret, 8 this month, andSunday Rose, 10 — witnessed Kidman’s cinematic transformation into a world-weary LAPD detective, they offered her a new nickname.

“They called me ‘granny,’ ” the 51-year-old actress told theLos Angeles Timesin a new profile. “They’re like, ‘You’re ourgrannynow.’ ”

“And she’s just like, ‘Whatever you do, never,everdo that,’ ” Kidman continued. “So I won’t be dressing up as their granny — even though that’s what they called me!”

Before theDestroyerpremiere at the Toronto International Film Festival in September, Kidman toldEntertainment Tonightabout herkids’ view of her career.

“But it’s also interesting for them, I think, because they see me creating characters and, you know, they have vivid imaginations themselves and they construct stories, and so that’s all they know,” added theBig Little Liesstar.

Her kids may be making fun of her appearance inDestroyer, but Kidman is getting plenty of praise from the Hollywood Foreign Press Association. Earlier this month, the star raved to PEOPLE about getting aGolden Globe nominationfor her role.

“It was such a risk, so to be acknowledged — the Hollywood Foreign Press is so good at that because they acknowledge these small films that would really struggle if they didn’tget this kind of celebration,” she said.
