The girls say that Letourneau was a strict parent with definite rules for how her daughters should act and dress. “She literally cut the padding out of my bra once,” Audrey told the show.

Fualaau was the more lenient parent, according to the girls.

“He definitely feels like a young dad now that I’m at that adult age to where I can go to a bar,” Audrey told the show. “He’s like a ‘friend dad.'”

On the show, Letourneau said she did not realize her actions were illegal.

“If someone had told me, if anyone had told me, there is a specific law that says this is a crime I did not know,” she said.

“I’ve said this over and over again. Had I’d known, if anyone knows my personality. Just the idea, this would count as a crime.”

When asked if she thought she was wrongly convicted, Letourneau replied, “absolutely.”
