Born in San Sebastián, the daughter of a social worker mother, Font enjoyed music since an early age. At age nine, Font began a formal training in music by taking musical classes. Her family later moved to the San Juan area of Santurce, where they were neighbors with Manuel Mendez Ballester, a very well known playwright of the era. Ballester discovered her and he invited her to a radio show he produced at the time, named "La Escuela del Aire" ("School on Air").
