Fustec was born in Paris to a Venezuelan mother and a French father.[1] She wrote poems and other texts before exploring her musical facet as "La Chica" starting in 2015.[2][3] According to her, her stage name came from the fact that "when I was a teenager, I used to have a very masculine energy. Once, an uncle started calling me 'chica' to remind me that I was a woman."[3]
In 2020, she released her album Cambio; as she stated in an interview, the title represents "the change I ask from heaven for the situation in Venezuela."[3] On March 19 of that year, she performed the opening concert of the Paris Music Festival at the Cité de l'Architecture et du Patrimoine.[1] Later that year, she released La Loba, dedicated to her deceased brother.[2]
She has lived in France and currently resides in Mexico.[3]
