Shabnam Khodayari told Insider that Kassia "Kassie" Mattis had her video reshared by James Charles.
Mattis said her love of makeup is because it's such a versatile skill that can be especially dramatic during seasonal holidays like Halloween and Christmas. "You can do anything with makeup. You can get as creative as you want," she said.
Khodayari said it was "still stressful to read things like, 'You're such a bad mom for exposing her to this.'"
"But at the same time, there are so many positive people seeing what she's doing and that she actually loves it. It's not forced on her," she added.
