For over 30 years, actress Mariska Hargitay, best known for her iconic role as Detective Olivia Benson on Law & Order: SVU, lived under the belief that her father was the man who raised her—Mickey Hargitay, a former Mr. Universe and bodybuilder-turned-actor. But in a deeply personal revelation, the Emmy-winning actress has now shared that her biological father is actually Nelson Sardelli, a renowned Italian singer and comedian.
This revelation has sent shockwaves through the entertainment world, not only due to its emotional weight but because it ties into the life of legendary Hollywood bombshell Jayne Mansfield, Mariska’s mother, whose own love life was frequently in the headlines during the golden age of Hollywood.
A Long-Held Secret Finally Comes to Light
In a candid interview with Vanity Fair, and further explored in her emotional documentary My Mom Jayne, Mariska confirms the rumors that have circulated for years: Mickey Hargitay was not her biological father.
“My mother had a brief relationship with Nelson after she separated from Mickey,” Mariska reveals. “But they later reconciled before I was born, and Mickey raised me as his own.”
For years, fans admired the close father-daughter bond between Mickey and Mariska. He was a pillar of strength after Mansfield tragically died in a car accident when Mariska was just three years old. Mickey, a Hungarian-American bodybuilder and actor, stepped up and raised Mariska and her siblings, shielding them from the relentless attention of the press.
The Clue Was in the Mirror
Mariska says she first suspected the truth when she was in her twenties. “I saw a photo of Nelson Sardelli and immediately saw the resemblance—it was like looking at a version of myself,” she told Vanity Fair.
When she confronted Mickey about it, he firmly maintained that he was her biological father. “That was the last time we talked about it,” she said. Mickey passed away in 2006 without ever addressing the subject again.
Despite the revelation, Mariska insists that she has never stopped considering Mickey her true father. “I’m Mickey Hargitay’s daughter—that is not a lie,” she says, reaffirming the deep emotional connection she shared with the man who raised her.
Meeting Nelson Sardelli: A Journey of Acceptance
At the age of 30, Mariska finally met Nelson Sardelli. It wasn’t an emotional reunion filled with tears and embraces—instead, it was cautious, quiet, and complicated.
“I told him, ‘I don’t want anything from you. I have a dad,’” she recalls. But with time, the wall she had built began to soften. Slowly, she developed a relationship not just with Nelson but also with his family.
Today, Mariska looks back on that period as one of healing and understanding. “It was about acceptance and truth. I wasn’t looking for a father—I was looking for clarity.”
Who Is Nelson Sardelli?
Nelson Sardelli, born in Brazil to Italian parents, rose to fame as a Las Vegas entertainer in the 1960s and ’70s. Known for his smooth vocals, charismatic stage presence, and comedic timing, he was a staple on the Vegas strip and in celebrity circles. His brief romance with Jayne Mansfield was covered by tabloids during the era when Hollywood royalty mingled with showbiz elite.
Although he never publicly claimed paternity, Sardelli expressed admiration and respect for Mansfield throughout his life. Now in his 90s, he maintains a quiet life, and his relationship with Mariska is private, yet reportedly cordial.
Hollywood’s History of Hidden Paternity
Mariska Hargitay’s story is just one in a long line of Hollywood paternity secrets. The entertainment industry, known for its glamor and mystique, has often shielded stories involving family truths, love affairs, and unexpected revelations. From Steve Jobs and Lisa Brennan-Jobs to Arnold Schwarzenegger‘s affair resulting in a secret son, celebrity legacies are often much more complicated behind the scenes.
What makes Hargitay’s story so touching is her grace in handling the truth. She has not used this revelation to create drama but to bring healing and understanding to her life story—and her mother’s.

Yet, behind the scenes, their marriage had its ups and downs, including brief separations and rumored affairs.
Mariska’s revelation shines a light on this lesser-known chapter of Mansfield’s life: her brief relationship with Sardelli, a man often overlooked in Mansfield biographies.

At its heart, Mariska Hargitay’s story is not about scandal—it’s about identity, forgiveness, and redefining what family means. Despite the shock, she maintains deep love and gratitude for Mickey Hargitay, crediting him for the person she became.
Today, Mariska is not only a respected actress and humanitarian but a powerful advocate for survivors of trauma, much like her Law & Order: SVU character. Her ability to face personal truths with bravery continues to inspire fans across the world.
