Amber Rose Hosts Third Annual SlutWalk in Downtown Los Angeles

Amber Rose is taking to the streets again to speak out against rape culture and slut shaming through her third annual SlutWalk in L.A. ... and her new man was front and center to support her.

Amber's hosting the women's rights event in Downtown, and she's got some special guests on hand to help her deliver her message -- one Blac Chyna and Just Brittany ... not to mention her BF 21 Savage.

BC and Brittany have both dealt with slut shaming this year -- Chyna through ex, Rob Kardashian, posting revenge porn ... and Brittany through online backlash she received for accusing her rapper BF Z-Ro of domestic abuse.

Amber rode out on a golf cart with Savage dressed as Captain Save a Hoe ... cape, wig and all. Savage even marched with her with a sign that read "I'm a Hoe Too."

Doesn't look like there are any tears this year either ... Amber's on cloud 9.
