"I'm really angry about the f**king trailer that was aired," the 24-year-old said on Monday.
In the clip, her mother, Barbara Evans, screams at her boyfriend David Eason and tells him he is the worst boyfriend she's ever had.
Evans ripped the network for painting her in a bad light and she was protective of Eason too.
"They make David look bad and myself!" she insisted.
Evans also complained that her employer exploited her arrest last year after an alleged fight with her ex-fiancé Nathan Griffith's girlfriend, Jessica Henry.
"They're forever showing my mugshot," she snapped.
"I cussed them out sobbing in tears last night," she said, explaining that the timing was awful for her. "I had at 5:45 am flight in the morning to L.A. to see a doctor about my health."
And Evans also lashed out at her co-star, who she thinks gets special treatment: "As always Chelsea Houska is the golden child as usual."
