Mariska Hargitay has built a legacy of strength, justice, andresilience as the beloved Olivia Benson on NBC’s Law & Order: Special Victims Unit. For over two decades, she’s portrayed a fierce detective and advocate for survivors — but behind the scenes, Hargitay has been quietly grappling with a personal truth that’s shaped her identity in ways few knew.
In a powerful and deeply emotional moment, Mariska Hargitay has finally revealed a shocking family secret she’s kept hidden for over 30 years. The revelation, which she shares in her directorial debut My Mom, Jayne, changes everything the public thought they knew about her Hollywood lineage.
A Daughter of a Hollywood Icon
To understand the magnitude of Mariska’s revelation, it’s important to remember her origin. Born in 1964, Hargitay is the daughter of Jayne Mansfield, the glamorous blonde bombshell of 1950s cinema, and Mickey Hargitay, a former Mr. Universe and bodybuilder who became a pop culture figure in his own right.
Growing up in the shadow of fame and tragedy, Mariska’s childhood was far from ordinary. When she was just three years old, she was involved in a horrific car crash that killed her mother, Jayne, along with two others. Miraculously, Mariska and her two brothers, who were asleep in the backseat, survived. It was a life-altering event that would leave deep emotional scars.
“I’ve lived with loss for most of my life,” Mariska has said. “It left a hole that I don’t think ever fully heals.”
The Shocking Secret Mariska Discovered in Her 20s
Though Mariska had always believed that Mickey Hargitay was her biological father, her world shifted when, at the age of 25, she was told something unexpected: her biological father was actually someone else — Nelson Sardelli, a charismatic Italian-born singer and entertainer who once had a romantic relationship with Jayne Mansfield.
The revelation wasn’t just surprising — it was earth-shattering.
“This changed everything for me,” Mariska admitted. “I felt like I didn’t know who I was for a while.”
It took her years to fully process the news. Out of respect and love for Mickey, the man who raised her with devotion, Mariska kept the truth to herself. It wasn’t until she turned 30 that she finally met Nelson Sardelli face-to-face, an emotional moment that helped her begin the long journey of self-discovery.
Meeting Her Biological Father and Half-Siblings
When Mariska eventually met Sardelli, it wasn’t just about understanding her DNA — it was about rediscovering her own story. Sardelli, who is now in his late 80s, welcomed her with kindness. Mariska also learned she had two half-sisters on her father’s side, deepening her connection to a part of her family she never knew existed.
The emotional reunion is featured in My Mom, Jayne, where the audience sees not only her evolving relationship with Sardelli but also the process of Mariska unpacking decades of silence and shame.
“For so long, I carried this alone,” she said. “Now, I realize sharing it doesn’t weaken the love I have for the man who raised me. It just adds more depth to my understa
nding of myself.”
‘My Mom, Jayne’ — A Tribute and a Reckoning
The revelation is only part of the emotional journey that My Mom, Jayne delivers. The documentary film, which premiered at the 2025 Cannes Film Festival, serves as a tribute to Jayne Mansfield’s legacy, as well as a raw exploration of the truth behind her public persona.
Hargitay’s role as director allowed her to take control of the narrative — not just of her mother’s, but of her own.
“I wanted to reclaim her story,” she explained. “So much of who my mother was got lost in headlines and mythology. But she was a brilliant woman, a loving mother, and much more than a sex symbol.”
The film doesn’t shy away from revisiting the 1967 car crash or the personal struggles Jayne faced in her career. But it’s also filled with intimate home videos, personal letters, and interviews with those who knew her — including Mariska’s new extended family.
The Impact on Her Identity
Mariska Hargitay’s identity has always been shaped by loss, love, and legacy. But this new layer of truth forced her to re-evaluate everything she thought she knew.
“There’s power in knowing the whole story,” she says. “It doesn’t erase the past. It just adds to it.”
Despite the complexity, Mariska remains deeply grateful to Mickey Hargitay, who she still considers her “real dad” in every way that matters. “He was the one who showed up, who tucked me in at night, who raised me with strength and compassion.”
A Champion for Survivors — On Screen and Off
Beyond her personal journey, Mariska has used her platform to support others facing trauma. In 2004, she founded the Joyful Heart Foundation, an organization that supports survivors of sexual assault, domestic violence, and child abuse.
Her activism isn’t just symbolic. She produced the HBO documentary I Am Evidence, which brought attention to the thousands of untested rape kits sitting in evidence rooms across the U.S. It was a powerful call to action and a direct extension of her SVU role.
In a powerful 2024 essay, Hargitay also disclosed that she was sexually assaulted in her 30s by a male friend. The experience, she says, made her even more determined to fight for survivors and to end the culture of silence.
A Full, Honest Life
Mariska Hargitay’s story is one of transformation — from tragedy to triumph, from secrets to truth. Married since 2004 to actor Peter Hermann, the couple shares three children: August, Amaya, and Andrew. Family, for Mariska, is both her anchor and her inspiration.
“My life has been shaped by pain and joy, loss and healing,” she reflected. “But I’ve learned that the truth sets you free — even if it takes 30 years to tell it.”
Final Thoughts
In revealing this long-held family secret, Mariska Hargitay isn’t just changing how the world sees her — she’s changing how we think about identity, family, and resilience. With My Mom, Jayne, she’s given us a rare glimpse behind the Hollywood curtain — and into the heart of a woman who has always been a survivor, both on and off screen.
