"It's heartbreaking. It makes me sick," she began. "How is this the world we live in? This is just like being retraumatized."
Smithline is one of three women who currently have lawsuits against the artist, while over 15 women -- including actress Evan Rachel Wood -- have made claims of abuse. Manson has denied all allegations.
"It's just showing the point that the world doesn't really care if you rape and if you beat and hurt all these [women], you can do whatever you want, basically, if you have money and you're a guy and you're famous," Smithline said.
She also called out the "Famous" rapper for including Manson in the program, saying he was "enabling a rapist." She added, "He's enabling an abuser and not just [of] one girl."
A spokesperson for Manson called the singer an "integral part" of Sunday Service, according to the outlet, and said it is "nobody's business" if Manson is following Christianity.
In February, Smithline first publicly accused Manson of abuse in an Instagram post, alleging he gave her "rules" shortly after they began dating and she would "get in trouble for any behavior he didn't approve of."
"There was abuse, sexual violence, physical violence and coercion," she added. "I still feel the affects everyday."
