“Riverdale” star Camila Mendes will be attending the Project HEAL SF Gala on Saturday to help break the stigma surrounding eating disorders.

On her Instagram account, the actress penned a lengthy letter addressed to her fans about her and her sister’s struggle with eating disorder. She also expressed her excitement over her partnership with Project HEAL. Mendes will be auctioning a day on the set of The CW series and hopes everyone can participate.

The third annual Bay Area gala will be held at the Levi Stadium in Santa Clara, California from 7 p.m. to 10 p.m. Tickets may be purchased at $350 for young professionals, $500 for general admission, $3,000 for the activist ring, $5,000 for the recovery ring and $10,000 for the commitment ring. Donations are also accepted. Other information may be viewed via the organization’s official website.

Meanwhile, this is not the first time that Mendes is speaking about something that’s very close to her heart. Earlier this year, she also opened up about what it’s like being a Latina in Hollywood. While speaking with Coveteur, the Brazilian actress and model said that she never felt a connection with the roles she auditioned for until she landed the role of Veronica.

Despite the comic book character being an American, The CW decided to write the TV counterpart as a Latina. “Veronica came in and it was the perfect balance. She was Latina! They wanted her to be ethnic, but that wasn’t the point of her character. She wasn’t a stereotype. She was just an American Latina. And that is how I identify, I don’t need to play up anything. I am this character,” she said.

In “Riverdale,” Veronica recently reunited with her dad, Hiram (Mark Consuelos). Her relationship with her boyfriend, Archie (KJ Apa) is going well. But she will soon reunite with her ex-boyfriend, Nick (Graham Phillips), and Veronica will be faced with the option to turn to her darker side.

“Riverdale” Season 2 airs Wednesdays at 8 p.m. EDT on The CW.
