"The Hermann's really know how to show up for Halloween!!" replied one. A second said: "This is awesome. If there was a competition for the best Halloween family outfits, your family would win it hands down!"
A third added: "The Hermann's coming through with all the creativity. Y'all KILLED IT… but I knew you would."
Fans adored Mariska and her family's Halloween costumes
Mariska and Peter met on the set of Law & Order: SVU all the way back in 2001 when the Younger actor guest-starred in the police procedural drama.
They wed two years after their first date at the Unitarian Historical Chapel in Santa Barbara on 28 August 2004. Mariska wore a pale pink Carolina Herrera gown with her husband's initials and their wedding date embroidered into the lining.
Speaking of the moment she knew Peter was 'the one', Mariska said on The Drew Barrymore Show in January: "Our first date he asked me to go to church with him, and it was that day."

She explained: "I remember we went to church, and I am crying, and he thinks I am so moved by the sermon, and I am crying because I am like, 'I know I am going to marry him. I found my husband. I love him.'"
The proud parents welcomed August in 2006. Five years later, in 2011, they adopted their daughter Amaya, and soon afterward they adopted their son Andrew.
