May 19 (UPI) -- Law & Order: SVU icon Mariska Hargitay shares in a new documentary that Mickey Hargitay isn't her biological father like she and the world have long believed.
The actress discussed her parentage in My Mom Jayne, an HBO documentary about her late mom, model and actress Jayne Mansfield.
Mariska, now 61, discovered in her 20s that Italian singer and comedian Nelson Sardelli -- not Hungarian bodybuilder and actor Mickey -- is her actual birth father.
The Hollywood Reporter, EW.com, E! News, the New York Post and Today reported the news.
Also according to My Mom Jayne, which Mariska directed and which screened this weekend at the Cannes Film Festival, Mickey raised Mariska and two of her older siblings after Mansfield died at the age of 37 in a Louisiana car crash in 1967.
