Plastic surgeons have praised the Australian actress for maintaining her timeless appearance over the years. A few have shared insights into possible methods she might be using to preserve her youthful glow.

AI predictions suggest that if Nicole Kidman had not been a celebrity like her younger sister, Antonia Kidman, she might look far different than she does today.

The siblings were born to Antony Kidman, a psychologist, and Janelle Kidman, a nursing instructor, with Nicole arriving in June 1967 and Antonia following in July 1970.

Growing up in an intellectually stimulating household, Nicole and Antonia were immersed in discussions about politics and philosophy at the dinner table.

Their parents instilled in them a deep sense of curiosity, independent thinking, and a commitment to making a difference. “My mom always told us to ‘get a cause!'” the Academy Award winner revealed in an interview once.

Nicole’s passion for advocacy was deeply rooted in the values her parents imparted to her. Their influence defined her not only as an artist but also as a person.

Sadly, heartbreak struck in September 2014 when her father, Tony, passed away from a heart attack at 75. A decade later, in September 2024, her mother, Janelle, also died at 84.

Janelle’s passing was announced at the Venice Film Festival, where Nicole won Best Actress for “Babygirl.” Director Halina Reijn accepted the award and read her statement.

“Today, I arrived in Venice to learn shortly thereafter that my beautiful, brave mother, Janelle Ann Kidman, has just passed. I’m in shock and I have to go to my family, but this award is for her,” she expressed through Halina.

Nicole conveyed gratitude for her mother’s influence, saying she defined her life. She called the moment heartbreaking, acknowledging the profound connection between art and loss.

Her tribute reflected the deep impact her mother had on her life. As she mourned from afar, Nicole’s family in Australia came together to honor Janelle’s memory.

Antonia appeared somber as she visited their late mother’s home in Sydney following the loss. Carrying a bouquet of flowers from the property, she remained surrounded by loved ones as the family leaned on one another during the difficult time.

While navigating their loss, memories of their shared past reminded them of the strong foundation their parents had built. As a teenager, Nicole pursued acting with her parents’ full support, eventually achieving global fame. Despite her success, she continued to seek Janelle’s guidance.

The movie star, now a mother herself, has embraced the role with the same devotion her parents showed her. She shares two children, Isabella and Connor, with her first husband, Tom Cruise. With her current husband, Keith Urban, she has two daughters, Sunday and Faith.

Nicole’s love for motherhood goes beyond her own children, and she enjoys being surrounded by kids. “I just love kids,” she said in an interview, while admitting, “I prefer children to adults.”

Though that view has evolved, her affection remains. When Keith was in Nashville for his 2020 album release, Antonia moved in to help while Nicole filmed, bringing three of her six children.

Family has always been central to Antonia’s life, just as it has for Nicole. She shares four children, Lucia, Hamish, James, and Sybella, with her late former husband, Angus Hawley.

The couple married in February 1996 but later encountered challenges. Antonia addressed the public when she and Angus separated, acknowledging the difficulties their family faced.

“[…] Angus is currently in a clinic seeking help to deal with anxiety and depression. He has my full support, and we ask that people respect our family’s privacy at this time.”

Despite her support, their marriage ended in May 2007 following eleven years. Angus soon realized how difficult it was to maintain privacy while parting ways with such a high-profile family.

By 2009, the businessman admitted to battling substance abuse, describing that period as a time of depression, self-loathing, and loss of control. He acknowledged that while it was a dark chapter, he eventually took steps to overcome it.

Despite the obstacles of her past, Antonia, now 54, found love again and embraced a new chapter in her life. In 2010, she married Australian banker Craig Marran in an intimate ceremony at Kruger National Park in South Africa.

The next month, they celebrated in Sydney with family and over 100 guests. The newlyweds later relocated to Singapore for Craig’s job and welcomed two sons, Nicholas and Alexander.

Settling into life in Singapore brought significant changes for Antonia, including a shift in her career path. She began her journalism career in the 1990s as a researcher on Nine’s “Today” before becoming a lifestyle presenter.

Her parenting series, “The Little Things,” aired on Foxtel in 2002, followed by “The Bigger Things” in 2006. She later won ASTRA Awards for Favorite Female Personality in 2007 and 2008.

Managing six children, Craig’s travel, and a demanding media career became difficult, prompting her to pursue a law degree at Macquarie University. She graduated in 2019 and now works as a family lawyer and parenting coordinator at Mills Oakley in Sydney.

Nicole celebrated Antonia’s achievement on Instagram, praising her for balancing studies, motherhood, and a new career with grace. She also honored their mother, crediting her for shaping their family.

The celebrity believes that life’s challenges have only strengthened her bond with Antonia. She called having a sister a blessing, describing their relationship as deep and unbreakable.

The siblings have been through a lot and always supported each other. Despite being a few years apart—Nicole at 57 and Antonia in her early 50s—the sisters remain as close as ever.

In addition to their strong bond, Nicole’s seemingly ageless appearance has also drawn attention, sparking speculation about possible cosmetic enhancements. In a 2024 interview, Beverly Hills plastic surgeon Dr. Deepak Dugar weighed in, “Nicole looks stunning and absolutely at a new peak of her beauty.

Though it’s unclear what, if anything, Nicole has had done, Dr. Deepak noted that those seeking a similar timeless look have several options. He emphasized key factors for a timeless look, including Dysport for the neck, a skincare routine with active ingredients, and skin-tightening lasers, comparing their effects to regular workouts.

Deepak also mentioned the importance of a balanced diet and maintaining a stable weight to preserve a youthful appearance. According to him, maintaining a stable weight helps keep the skin firm.

Meanwhile, New York City facial plastic surgeon, Dr. Sam Rizk stated that Nicole’s youthful look is likely due to ultrasound skin-lifting treatments like Sofwave and surgical procedures such as a deep plane facelift and eyelid enhancement.

He added that many patients in their 40s seek similar treatments for a tighter jawline and refreshed eyes, with some even bringing the public figure’s photos for reference.

If the actress had led a life away from fame, her appearance might have reflected a more natural aging process. AI-generated images provide a glimpse into how she could have looked. Her silver hair would fall past her shoulders, framing her face, while her natural complexion would highlight the raw beauty of aging.

Nicole’s auburn hair might appear slightly faded, complementing the soft creases on her forehead and around her eyes, with a relaxed expression that highlights the natural aging process.

Waves of silvery-blonde hair would have enhanced her strong features, giving her a grounded and introspective presence. The signs of aging on her skin would have told a story of authenticity, untouched by Hollywood’s polished glow.

Her reddish hair, softened by age, would have framed her face with a serene yet serious look. Free from airbrushed perfection, her features would have shown the natural effects of aging.

Nicole Kidman and Antonia’s lives have been shaped by family, career shifts, and personal challenges, with Nicole embracing Hollywood’s beauty standards while Antonia pursued law and motherhood. Their journeys, from Sydney to global success, highlight deep family bonds and the choices that define them.
