Rosa Acosta is a fitness buff, a model and a ballet dancer, and she's making us wish we had become a ballerino. That's a thing, right? Everyone always says "ballerina," so isn't "ballerino" correct? We don't feel like Googling it. Too many pics of Rosa to ogle. She hails from the Dominican Republic and, judging by some of the comments throughout her Instagram, she may be the reason the phrase "the thirst is real" exists. Check for yourself.
