In 2025, the story of Mariska Hargitay’s real father made headlines, bringing a deeply personal family secret into the public eye. The beloved Law & Order: SVU star stunned fans when she opened up about her true parentage in a new documentary. For years, Mariska was known as the daughter of Mickey Hargitay, the charismatic actor and bodybuilder who raised her after the tragic death of her mother, Jayne Mansfield. However, recent revelations have confirmed that Mariska Hargitay’s real father is actually Nelson Sardelli, an Italian singer and comedian.
