Mariska Hargitay honors her mother, Jayne Mansfield, with new documentary

Her biological father is a singer named Nelson Sardelli, who had a (fairly public) relationship with Jayne for a few months after she and Mickey were divorced but while they were still together off and on.

Jayne Marie Mansfield (born November 8, 1950) is an American actor and model. She is the first child and eldest daughter of 1950s Hollywood sex symbol and Playboy Playmate Jayne Mansfield, with the putative father being Mansfield's ex-husband Paul Mansfield.

Mansfield was killed in a car crash in June 1967. She was going to New Orleans for a television interview when her car crashed into the back of a truck.
