Cardi B is sick of people assuming she's not black because she speaks Spanish.

She explained her ethnic background in a new video, in which she discussed getting mistaken for Mexican. 

"I'm not Mexican at all. I'm West Indian and I'm Dominican. I speak Spanish because I'm Dominican," Cardi explains. "And it's like, so what's the difference between Dominican and Mexican?' And it's like, everything.

People just don't be understanding shit," Cardi continued. "It's like, 'Cardi's Latin, she's not Black.' And it's like, 'Bro, my features don't come from...white people f*cking, OK?' And they always wanna race-bait when it comes to me...I have Afro features. 'Oh, but your parents are light-skinned...all right, but my grandparents aren't."

Cardi then said she's baffled that she isn't put in the same box as other Carribean artists.

"'cause it's crazy right because some island women, some artists that are from the same islands as me, people will be like, 'Oh they're Black,' but because Cardi speaks Spanish to people—she's not Black," Cardi explains. "Even though we have similar features, same skin complexion... but no, they want to not put Cardi in it because I speak Spanish."
