Mariska Hargitay Uncovers Shocking Family Secret with a personal revelation. The actress opened up about a long-hidden family truth in her new documentary, “My Mom, Jayne.” This emotional project, which premiered on May 17, 2025, at the Cannes Film Festival, allowed her to explore her roots like never before.
For decades, Hargitay believed that bodybuilder and actor Mickey Hargitay was her biological father. But there was a story only a few knew, and that story remained untouched for thirty years until now. The truth, though painful, has brought her clarity and helped her connect the missing pieces of her past.
What Family Secret Did Mariska Hargitay Reveal After 30 Years?
This secret has changed the way she views herself. For years, she believed that Mickey Hargitay was her birth father. He raised her, supported her, and played the role of a loving dad throughout her life.
However, in her twenties, Mariska found out that her real father was not Mickey. Her biological father was actually Nelson Sardelli, an Italian-born Las Vegas performer. The discovery wasn’t something she actively looked for. Instead, it came after she saw a picture of Sardelli and noticed a striking resemblance. This observation led her to ask questions she had buried for years.
Jayne Mansfield, Mariska’s mother, had reportedly reunited with Mickey while she was pregnant. To the outside world, they appeared to be a happy family. This decision was possibly made to avoid a scandal and protect her children’s image. For Mariska, that choice shaped her entire identity.
