The star held up a sign that read 'defund the police' as she walked in the peaceful protest in the Californian city.

She sported a cropped army green sweatshirt, some skintight black bike shorts and a pair of black and white Adidas sneakers.  

Ratajkowski kept her face covered with a red baseball cap, black Ray-Ban wayfarers and a black face mask. 

She previously took to her Instagram story with a sign she created that read: 'Dismantle power structures of oppression.'  

The I Feel Pretty star also shared video of the peaceful demonstration as protesters took a knee in front of City Hall.

She shared another photo of armed soldiers in front of a boarded-up storefront, writing: 'Who are you protecting? Who are you serving?'

Ratajkowski also used her story to call out social media activists, after #BlackOutTuesday started trending, taking over the #BlackLivesMatter hashtag with black squares instead of vital resources.

The Twilight alum slicked her blonde tresses in a half-up, half-down updo, as she cut a bandit chic look.
