Here Are the Key ‘Fundamentals’ of Mariska Hargitay’s 14-Year Marriage to Husband Peter Hermann

Mariska Hargitay, known for her role in "Law & Order: Special Victim's Unit," tied the knot with Peter Hermann 14 years ago.

The mother-of-three met Hermann on the set of "Law & Order" in 2001 and walked down the aisle three years later.

Hargitay had always wanted a big family. They share three children – son August, 12, eight-year-old daughter, Amaya, and Andrew Nicolas, six.

THE FUNDAMENTAL SECRET

Hermann and Hargitay told ET Online in an exclusive interview the secret to their happy marriage is that they have no secret. Hermann explained:

"Our son plays basketball, and his coach says, ‘Fundamentals, fundamentals, fundamentals,’ and I think when it comes to relationships, the fundamentals, in the end, are not that complicated."

He's quick to add that it "doesn't mean [the fundementals] are easy," just that it isn't complicated. The fundamentals of their relationship are "kindness, listen well and fight fair."

HAPPY FAMILY, STRICT FAMILY

The duo jokes that they run a tight ship at home, saying their children won't get to watch "Law & Order: SUV" until "they're, like, 40."

Hargitay doesn't shy away from talking about adoption. In one instance, a couple who had put their child up for adoption changed their minds a few days after the baby was adopted.

In addition, they love spending time together as a family, despite Hargitay and Hermann's busy schedule and demanding careers.

To date, Hargitay appeared in more than 459 episodes of "Law & Order: Special Victims Unit." She is a committed actress but always puts her family first.

FAMILY ALWAYS FIRST

Hargitay, a former beauty queen, said back in 2018 that "the beauty if families are made in so many different ways." She explained:

"Growing up, my family was made in such an interesting and unique way, and now I have that with my own family, and so I understand it."

Hargitay doesn't shy away from talking about adoption. In one instance, a couple who had put their child up for adoption changed their minds a few days after the baby was adopted.

Even though it was a difficult time for Hargitay and Hermann, she chooses to be open about the ups and downs in order to raise awareness for adoption.
