The photos come with warnings and disclaimers, including that the injuries were added using Photoshop. But Hubbard, whose own children played Rick and Carol in the photo series, has been slammed by some viewers.
One wrote on Facebook: "I like The Walking Dead, but it's an adult show for a reason! This is just disturbing." Another said: "WHY would anyone subject their children to this?"
Hubbard replied: "No child was harmed in the making of this .... it's pretend! These are MY children and their friends let's be respectful here. And those of you who don't like it... Don't look at it."
She told Gizmodo: "I don't see it as a big deal. The kids were all laughing, no children were harmed, no children even had zombie make-up on. It was all edited in Photoshop. They had a fun time killing zombies and running around."
And Hubbard admitted the children enjoyed filming the Negan scene the most.
"All the kids wanted to get dead. They had a blast!" she said.
