Mariska Hargitay comes from prominent Hollywood lineage, and while she's made a name for herself thanks to Law & Order, that's not to say there isn't some strong cred behind her name.
The actress is the daughter of fellow actors Mickey Hargitay and Jayne Mansfield, the latter being one of the 1950s' biggest sex symbols and a Golden Globe-winning star.
On what would've been her 90th birthday, Mariska took to social media on Wednesday with an old promotional shot of her mom in a white dress, as fabulous as ever.
"Happy birthday Mama. We live to love you more each day," she captioned her tribute, receiving a barrage of birthday wishes in return from the likes of close friend Ali Wentworth and Hilary Swank.

Several were left stunned by how much Jayne and Mariska looked alike, with one fan commenting: "Still can't get over how much you look like your mama."
Another even gushed: "YOU are her legacy. You can see her so clearly in you & I know she'd be proud to call you her daughter."
Mariska was born of a six-year marriage between Jayne and Mickey, a Hungarian-American actor who was also crowned Mr. Universe in 1955.
However, famous as Jayne was – she was a Playboy Playmate and starred in movies such as A Guide for the Married Man and Dog Eat Dog – her fame was unfortunately short-lived, having died in a car crash in 1967. Mickey passed away in 2006.

Before her untimely death, Jayne was married three times – she was known for publicizing much of her personal life and even publicity stunts – Mariska's father being her second husband. She first married Paul Mansfield in 1950, and before their 1958 divorce, they had one daughter, Jayne Marie Mansfield.
With Mickey, who she was married to from 1958 to 1964, she had three children. Her eldest is Mickey Hargitay Jr., 64, then they had Zoltan, 62, and her third with Mickey is Mariska, who is 59. Her fifth and youngest child is Tony Climber, 58, whose father is Matt Climber. Jayne was married to him from 1964 until 1966.
