Law & Order star Mariska Hargitay, 61, shoots husband of 20 years a loving look during rare date night in Cannes

Mariska Hargitay seemed to be inspired by old Hollywood glamor as she attended the annual Foundation for AIDS Research gala in Cannes Thursday night. 

The actress, 61, who has been at the film festival promoting her documentary My Mom Jayne, about her later mother, blonde bombshell Jayne Mansfield.

The Law & Order: SVU star stepped out in a stunning white gown with a silver beaded halter neck and a short train from the French fashion house Patou.

In keeping with her classic look, the Emmy winner had her thick, chestnut tresses styled in a sleek updo. She chose to let her natural beauty shine out wearing a sensuous smoky eye with a hint of blush and a soft pink lip. 

Hargitay accessorized with diamond earrings, rings, a bracelet and a purse from gala sponsor Chopard. 

Sharing the look on social media she thanked her makeup artist Georgi Sandev and hair stylist David von Cannon for their help in making her picture perfect for the fundraiser.

Peter Hermann, 57, looked elegant in a black tuxedo and shirt, which highlighted his salt and pepper hair and beard.

The couple, who have been married for more than 20 years and share three kids together, seemed like newlyweds, holding hands as they made their way toward the storied Hotel du Cap-Eden-Roc. 

Sharing a photo of herself and Hermann on social media, Hargitay played off the couple’s bridal look tagging the photo with #isaidyes, which many future brides use to announce their engagements. 

The pair met when Hermann was a guest star on SVU in 2002. 

Their son August, was born in 2006, and they adopted daughter Amaya and son Andrew, both 13, in 2011.

All three kids accompanied their parents to Cannes, but Thursday night was a rare public date night for their mom and dad. 

Giving a shoutout to charitable organization, Hargitay wrote, ‘Thank you @amfarfor the extraordinary work you do in the fight to end the global aids epidemic.’

Since it’s founding in 1985, ‘amfAR has raised more than $920 million in support of its programs and has awarded more than 3,800 grants to research teams worldwide,’ according to the organization’s website.

It was a rare public date night for the actress, 61, and husband Peter Hermann, 57, who seemed more like newlyweds than a couple who have been married for more than 20 years
