Mariska Hargitay says that in her 20s, she discovered that the man who raised her was not her biological father — but she has no regrets: 'I grew up where I was supposed to.'

Mariska Hargitay’s new documentary, “My Mom Jayne,” doesn’t just explore the life of her famous mom, actress Jayne Mansfield. The film, which premiered at the Cannes Film Festival on May 17, also reveals the real identity of her biological father.
