Mariska Hargitay looked incredible as she channeled old Hollywood glamour at the Friday night Tribeca Festival premiere of her new documentary My Mom Jayne.

She was joined by her longtime husband, 57-year-old actor Peter Hermann, and their three children: August, 18, Andrew, 12, and Amaya, 14.

The 61-year-old Law & Order mainstay is the daughter of the late pinup star Jayne Mansfield and Hungarian-American actor and bodybuilder Mickey Hargitay.

In her new movie, she dropped a bombshell revelation — that her biological father is former Las Vegas entertainer Nelson Sardelli and not Hargitay, the man who raised her.

For the special occasion, the actress dazzled in a glitzy gown boasting a champagne-colored beaded floral top with a matching shawl, long black skirt, and white opera gloves.

Ahead of the star-studded event, Mariska took to Instagram to interact with her 3.4 million followers.

Sharing a precious photo of her blonde bombshell mother holding her as a baby, she wrote, ‘Thank you for the incredible outpouring of love for #MyMomJayne.

‘It means the world to me. Because of the beautiful, overwhelming response, WE’VE JUST RELEASED MORE TICKETS for our @tribeca premiere at @carnegiehall!’

She concluded the note, ‘I can’t wait to share this story with you. See you THIS Friday, June 13th. #LinkInBio.’
