Rose, who usually keeps her hair super short, is really good at changing up her image. Wiz Khalifa's ex has gone incognito in other Instagram shots by simply becoming a blonde or a redhead for the day.
She spoke with ET about the mission of this walk, set in Los Angeles on October 3.
"It brings awareness to a lot of men and women that [slut-shaming, victim blaming, rape and sexual assault happen] every single day," Rose explained. "It has happened to me on so many different levels. … I really have been through some things. ... I lived it. Maybe one day I'll tell me story. Until then I feel like if I can just help other women get through what they've been through, then that can also help me get to the next level in my life."
