Amaia Romero is a Spanish pop singer who began singing at the age of eleven when she took part in the kids' talent show Cántame una canción. A couple of years later she took part in the talent show El Número Uno but was eliminated in the sixth week.
In 2017, she auditioned for the ninth season of Operación Triunfo and was selected along with fellow competitor Alfred García to represent their home country at the Eurovision Song Contest 2018 in Lisbon with the song "Tu canción", where they were directly qualified for the final due to the country being a "Big Five" nation. They finished in 23rd place with 61 points.
