Amber, 32, was joined on stage in downtown LA by her pregnant friend Chyna, who is expecting a child with Robert Kardashian.
Slut Walks have been organized in recent years after a police officer told female students in Toronto in 2011 that women “should avoid dressing like sluts in order not to be victimized”
On her website, Amber explained why she organised the event, writing: “The idea that there is some aesthetic that attracts sexual assault or even keeps you safe from sexual assault is inaccurate, ineffective and even dangerous.
“No more sexual violence, no more victim blaming, no more derogatory labels, no more gender inequality.”
A number of religious protesters reportedly attended the “Slut Walk” to oppose the event.
Amber is appearing on the current series of Dancing With The Stars, alongside Little Women: LA‘s cast member Terra Jole who also showed up to show her support for the “Slut Walk” event.
