Nicole Kidman learned how to do her make-up by watching professionals on movie sets

She told WWD: "When you're working with someone like [director] Baz Luhrmann and [costume designer] Catherine Martin, there's a very specific look they want for the character.

"I started to realize, as I was being created by others and experimenting, they were teaching me how to use makeup in particular ways and create characters. I could then go and use that in real life."

She added: "When I started experimenting with make-up and skin care myself, I went through so many different stages: lots of masks, this and that. I learned I can change aspects of my face, augment things, and it became much more creative and exciting."

Nicole recently signed up to be a brand ambassador for cosmetics company Clé de Peau Beauté and she insisted she was already a fan of their products before the deal came about.

She told the publication: "I'd already been using so many of their products. It wasn't like I was going to have to discover them, and I was in."

Nicole previously revealed changing her look so many times over the years took a toll on her hair. She used to sport long curls, but she previously revealed she lost her "ringlets" because she "tortured them to death" by straightening her hair so much.

She told Who magazine: "I really wanted to have that suntanned skin and long blonde hair. I wanted to conform and be the Aussie beach girl. And I was never going to be that ...

"I wish I had my curls back. I tortured them to death. I always say, 'Don't ruin the ringlets!'"

She later added to the The Sunday Morning Herald: "Do I wish that I hadn't screwed up my hair by straightening it all the time? Sure."

Nicole also admitted she wishes she'd been "more careful" with sun cream in her younger years after previously dealing with skin cancer. She added to the publication: "I've had skin cancer; do I wish I'd been more careful with the sun? Yes, to all those things. "But am I grateful to be around? Oh, yeah. And am I willing to share my knowledge, what I've learnt along the way? Absolutely."
