Nicole Kidman, 57, shows off her ageless visage at Palm Springs International Film Awards after sharing the secret to her youthful looks

Nicole Kidman looked radiant as she attended the Palm Springs International Film Awards in California on Friday night.

The 57-year-old showed off her line-free face as she walked the red carpet at the prestigious event.

The Moulin Rogue star stunned in an oceanic themed dress with a corset bust and fish scale design.

It was accentuated by a mermaid-style skirting board in deep sea green silk with a short train.

Nicole added gold earrings with an amber stone and a ring, but otherwise skipped the accessories.

The strawberry blonde wore her tresses in soft waves and opted for a clean and fresh makeup look with a natural pink lip.

During the event, Nicole broke down in tears on stage as she paid tribute to her late parents.

The actress gave an emotional speech as she accepted the International Star Award from Jamie Lee Curtis.

Nicole thanked her parents for teaching her resilience and giving her the “love and strength” she needed to move forward in life.

She accepted her award on stage at the Palm Springs Convention Center and said, “I went home for Christmas. I’ve lost both of my parents, and I’m in a place of, okay, this is different now.

“They’ve given me the resilience and they’ve given me the love and they’ve given me the strength to keep moving forward.”

Her mother Janelle tragically died just hours before she was named Best Actress for her role in Babygirl on the final day of the Venice Film Festival in September, a huge achievement.

It comes after one of Nicole’s best-kept beauty secrets was revealed.

In October, the Oscar-winning actress wore a hairpiece as she attended the premiere of Netflix’s Spellbound in New York City.

The Hollywood star wore the weave to add volume to her strawberry blonde locks and give her a more youthful appearance.

However, Nicole’s extra hair and natural locks appeared to be a slightly different color as she let her locks fall over her shoulder.

The tissue was on top of her head and visible above her forehead.

Hollywood stars often wear wigs and hair extensions to achieve a more youthful appearance, as hair thins and loses volume with age.

Nicole also showed off her smooth, porcelain face with a natural makeup palette at the premiere.

She looked ethereal in a white lace dress as she posed on the red carpet.

Nicole’s habit of wearing wigs in Hollywood films has earned her a cult following over the years.

She has not shown her natural hair on screen since the early days of her career and wears wigs almost exclusively for film roles.

One of the few times Nicole showed off her naturally curly hair was in her first feature film, 1983’s BMX Bandits.

The Hours star has previously credited healthy lifestyle choices as the secret behind her age-defying complexion.

In 2007, Nicole denied having cosmetic surgery and said her flawless skin was the result of her healthy lifestyle.

“Honestly, I’m completely natural,” she told Marie Claire at the time.

‘I wear sunscreen and I don’t smoke. I take care of myself. I’m very proud to say that.’

However, in 2011, she admitted to getting Botox during an interview with German magazine TV Movie.

“I’ve tried a lot of things, but other than exercise and good nutrition, most things don’t make a difference,” she said.

‘I even tried Botox, but my face no longer looked nice afterwards. Now I don’t use it anymore and I can move my forehead again.’

Nicole previously also showed her collection of anti-aging serums from the plant-based beauty brand Seratopical.

In a sponsored video shared to Instagram, she was seen using the Radiant Face & Neck Serum, which retails for $40 (AUD$60).

She then demonstrated another of her favorite products, the Clarity Foaming Cleanser, which costs US$25 (AUD$37).

Finally, Nicole held up the Adoring Eye Serum as she winked at the camera. The product also retails for USD$40 (AUD$60).
