In a Vanity Fair interview published May 17, 2025, Hargitay said she learned that Italian singer and entertainer Nelson Sardelli was her biological father. She has continued to describe Mickey Hargitay as her father because he raised her and was the parent she knew. The 2025 documentary My Mom Jayne also introduced viewers to two biological half-sisters through Sardelli: Giovanna Sardelli and Pietra Sardelli.
Mariska Hargitay’s five traditionally listed siblings
| Sibling | Relationship traditionally reported | Family connection |
|---|---|---|
| Mickey Hargitay Jr. | Older brother | Son of Jayne Mansfield and Mickey Hargitay; Mariska’s maternal brother and household brother |
| Zoltan Hargitay | Older brother | Son of Jayne Mansfield and Mickey Hargitay; Mariska’s maternal brother and household brother |
| Jayne Marie Mansfield | Older maternal half-sister | Daughter of Jayne Mansfield and Paul Mansfield |
| Tony Cimber | Younger maternal half-brother | Son of Jayne Mansfield and Matt Cimber |
| Tina Hargitay | Half-sister in the conventional Mickey-linked family account | Reported as a daughter of Mickey Hargitay from an earlier marriage; the 2025 paternity disclosure makes a biological relationship with Mariska uncertain |
The wording matters. Mickey Jr. and Zoltan remain Mariska’s brothers through their mother and through the family in which they grew up together. However, because Mariska now identifies Nelson Sardelli—not Mickey—as her biological father, it is too broad to describe Mickey Jr. and Zoltan as her confirmed biological full brothers. Tina is best described as a half-sister in the long-established family account connected to Mickey, rather than as a confirmed biological paternal half-sister.

#1 Best Overall
1. Mickey Hargitay Jr.
Mickey Hargitay Jr. is Mariska’s older brother. Public biographies identify him as a son of actress Jayne Mansfield and Hungarian-born bodybuilder and actor Mickey Hargitay. He and Zoltan were the two brothers who shared Mariska’s immediate childhood household after her birth.
Mickey Jr. was also one of the family members who appeared with Mariska at her Hollywood Walk of Fame star ceremony in November 2013. His memories are included in the family story surrounding My Mom Jayne, Mariska’s 2025 documentary about her mother’s life and legacy.
Beyond those public appearances and family references, relatively little reliable current biographical information about Mickey Jr. is consistently documented. There is no need to fill that gap with unverified claims about his occupation, residence, marriage, or private life.
2. Zoltan Hargitay
Zoltan Hargitay is Mariska’s other older brother and, like Mickey Jr., is publicly identified as a son of Jayne Mansfield and Mickey Hargitay. The brothers and Mariska were together in the car on June 29, 1967, when a crash killed Mansfield. Contemporary and later biographical accounts describe all three children as surviving.

His perspective is significant because the film focuses not only on Mansfield’s celebrity image but also on what her children remember about her and the aftermath of her death.
Mariska was three years old when Mansfield died. After the crash, Mickey Hargitay raised Mariska and her brothers with his wife, Ellen Siano. That upbringing is the reason Mickey’s parental role remains central to Mariska’s understanding of her family, even after the 2025 revelation about her biological father.
3. Jayne Marie Mansfield
Jayne Marie Mansfield is Mariska’s older maternal half-sister. She was born during Jayne Mansfield’s first marriage to Paul Mansfield, making her Mariska’s half-sister through their mother.
Jayne Marie has been one of the more publicly visible members of the Mansfield family and has worked as a performer. She attended Mariska’s November 2013 Hollywood Walk of Fame ceremony alongside Mickey Jr. and Zoltan. She is also part of the family material connected with My Mom Jayne.
The surname is important: her name is Jayne Marie Mansfield. It should not be shortened to an incorrect surname when identifying her in a family tree or documentary guide.
4. Tony Cimber
Tony Cimber—also called Antonio or Anthony Cimber in some references—is Mariska’s younger maternal half-brother. He is the son of Jayne Mansfield and director Matt Cimber, Mansfield’s third husband. Tony and Mariska therefore share their mother, not their father.
Tony belongs to the blended group of Mansfield’s children from different relationships. Family coverage connected with My Mom Jayne includes him in the broader story of how Mansfield’s children remembered their mother and remained linked after her death.
Because Tony has maintained a lower public profile than Mariska, Jayne Marie, or the better-known Mansfield family figures, claims about his present career, location, relationships, or personal life should not be treated as established unless supported by a direct and reliable source.
5. Tina Hargitay
Tina Hargitay is traditionally described as Mariska’s paternal half-sister because she is identified as one of Mickey Hargitay’s daughters from an earlier marriage. In the family structure reported for decades, Tina was Mariska’s half-sister through Mickey—the man who raised Mariska.
Mariska’s 2025 disclosure requires a more careful description. If Nelson Sardelli was Mariska’s biological father, Tina cannot automatically be called Mariska’s confirmed biological paternal half-sister. The safest accurate wording is that Tina is her half-sister in the established Mickey-linked family account and part of the family relationship associated with the man Mariska regarded as her dad.
Tina is less extensively documented in public sources than the other siblings. Reliable coverage identifies her family connection but does not provide a firm basis for adding details about her age, work, residence, spouse, children, or current relationship with Mariska.
2025 update: Mariska’s biological half-sisters through Nelson Sardelli
While discussing My Mom Jayne, Hargitay publicly said that Nelson Sardelli was her biological father. She had grown up believing that Mickey Hargitay was her biological father, and she said Mickey denied the claim when she confronted him. Hargitay nevertheless maintained the emotional distinction between biology and parenthood: Mickey was the father who raised and loved her.
The documentary coverage names Giovanna Sardelli and Pietra Sardelli as Hargitay’s biological half-sisters through Nelson Sardelli. They are not included in the traditional five-sibling headline because older entertainment biographies were organized around the Mansfield-Hargitay household and the family relationships known before Hargitay discussed her paternity publicly.
Rank #4
Some reporting has been inconsistent about the total number of Sardelli’s daughters. The strongest current coverage specifically identifies Giovanna and Pietra in connection with Hargitay’s story, so those are the names that can responsibly be added. The list should not be expanded beyond them without stronger primary documentation.
How the family relationships fit together
- Jayne Mansfield and Paul Mansfield: Their daughter was Jayne Marie Mansfield.
- Jayne Mansfield and Mickey Hargitay: Their sons included Mickey Hargitay Jr. and Zoltan Hargitay. Mariska was raised within this family and household.
- Jayne Mansfield and Matt Cimber: Their son was Tony Cimber.
- Mickey Hargitay’s earlier family: Tina Hargitay is identified in older biographical and obituary coverage as one of Mickey’s daughters.
- Nelson Sardelli: Hargitay identified him in 2025 as her biological father; Giovanna and Pietra Sardelli are named as her biological half-sisters through him.
This is why different articles can appear to give different answers without necessarily describing entirely different families. One count follows the siblings associated with Mariska’s childhood family. Another follows biological parentage revealed later. Those categories should not be merged without explanation.
Family timeline
- Jayne Mansfield’s first marriage: Jayne Marie Mansfield was born to Jayne Mansfield and Paul Mansfield.

- November 2013: Mickey Jr., Zoltan, and Jayne Marie joined Mariska at her Hollywood Walk of Fame star ceremony.

What My Mom Jayne adds to the story
My Mom Jayne: A Film by Mariska Hargitay is a 2025 HBO original documentary directed by Hargitay. HBO’s description presents it as her effort to understand and embrace Jayne Mansfield’s legacy, while the film’s family conversations broaden the story beyond Mansfield’s familiar public image.
The documentary is especially relevant to the sibling question because it brings family recollections into a story that has often been told through old Hollywood headlines, photographs, and Mansfield’s celebrity biography. Mickey Jr., Zoltan, Jayne Marie, and Tony are represented in the family material associated with the film. A person’s participation in the documentary, however, should not be taken as proof of every separate biographical detail sometimes repeated online.
For viewers who want to see the source of the 2025 family update, they can watch My Mom Jayne through a current Amazon Video listing if one is available in their market. Digital availability, rental options, and regional access can change, so the listing should be checked before publication or viewing.

Readers who want more context on Mansfield’s career, public image, and family history may want to read Eve Golden’s Jayne Mansfield: The Girl Couldn’t Help It. It is a broader biography of Mansfield rather than a replacement for the family’s own account in My Mom Jayne; edition details and availability can vary.

The bottom line
The conventional answer to “Who are Mariska Hargitay’s five siblings?” is Mickey Hargitay Jr., Zoltan Hargitay, Jayne Marie Mansfield, Tony Cimber, and Tina Hargitay. Mickey Jr. and Zoltan are her maternal brothers from the household in which she grew up; Jayne Marie and Tony are her maternal half-siblings; and Tina is linked to her through Mickey in the traditionally reported family structure.
Best Value
But the current answer needs one more layer. Hargitay’s 2025 account identifies Nelson Sardelli as her biological father and names Giovanna and Pietra Sardelli as biological half-sisters. The five-sibling list remains a useful description of the established Mansfield-Hargitay family story, but it is not the complete biological sibling count.
