Charis McGowan Before her ninth and final headlining show in Buenos Aires’ Movistar Arena last week, Argentine singer-rapper Nicki Nicole offered everyone in her dressing room a drink — of maté herbal tea. Speaking fast and eagerly (which she later apologized for), she said, “Ah, but if maté is too sour for you, you should try terere — you’d love that, it’s so refreshing!” This sort of dorky openness puts everyone around her at ease, earning her a reputation for being humble and approachable despite her status as one of Latin America’s most in-demand Gen-Z stars and singer-songwriters. Since releasing her third album “Alma” last May, Nicole has earned three RIAA-certified plaques for singles including “8 AM” with Young Miko, “Dispara***” with Milo J, and “que le pasa conmigo” with Rels B.
