The actress took home the Golden Globe for her role in the HBO drama last year.
The second time around is just as sweet and special!
Nicole Kidman received her second Golden Globe nomination for her role as Celeste Wright in Big Little Lies, and opened up to ET's Nischelle Turner about the amazing honor.
"We were just so, so happy and thrilled because Big Little Lies is such a passion for all of us," Kidman said while at the Bombshell premiere at Regency Village Theatre in Westwood, California, on Tuesday. "And to have it acknowledged in this way by the Hollywood Foreign Press was just, it was so important. And also the Critics Choice, and all of those acknowledgements, just because the subject matter in this is still -- yes, there's all of the sort of the hoopla around it -- but if you take all that, strip all that away, and hopefully get to what the show is actually about, that's still there in such a different way this season."
Last year, Kidman took home the Golden Globe for Best Performance by an Actress in a Limited Series or a Motion Picture Made for Television for her Big Little Lies role. She has won a total of four Golden Globes.
Currently, Kidman is promoting Bombshell in which she portrays Gretchen Carlson. The upcoming drama tells the story of the women at Fox News who exposed the Roger Ailes sexual misconduct scandal and took down the TV titan. The actress has been having a blast with co-stars Charlize Theron and Margot Robbie while on the press tour.
"We have fun, we have loads of fun," Kidman told ET. "They both have amazing senses of humor and they're just up for anything. And obviously Margot's an Aussie, so we immediately have incredible, sort of, history together, because of that we just have a second language. And Charlize, we've made an honorary Aussie."
That night, Robbie also told ET about the sage advice that Kidman has given her. "One of the first things Nicole said to me was like, 'Any mistakes I have made, let me tell you so you don't have to make them as well,'" she said. "They've both been amazing mentors."
As for Kidman, she believes it's important to pass on one's knowledge to other women and younger actors.
"I think the most important thing is passing on your knowledge," Kidman expressed. "I've worked now with so many young women, and obviously I'm raising young girls right now, and if someone came up to my children and was willing to share their knowledge with no agenda, nothing other than just hoping that they have a great life, and in some way help them, I would be so grateful to them as a mother, so that's what I try to do."
Bombshell arrives in theaters on Dec. 20. See Kidman's amazing transformation in the video below.
