DeBose, who identifies as Afro-Latina and queer, told People en Español that she hopes to use her growing platform to advocate for and inspire the Afro-Latina and LGBTQ communities.
"I take this very seriously. I am a 'positive vibes only' person, especially in my social media presence," she said, adding, "I don't want to give anyone a reason to put these communities down. That being said, I say what I mean and mean what I say. Afro-Latinos have been underrepresented in our industry."
Continued DeBose: "I am excited to continue to be a part of moving the needle forward so we can reach a day where there is balance in how we represent the beautiful spectrum of Latinos, and not just one 'traditionally Latino' prototype."
