Aitana began teasing her debut studio album in March 2019 which was intended to be a new EP that would be the second of a trilogy. That same month, the singer announced that she would be embarking on an intimate promotional concert tour the month after produced by Los40. At the tour's first stop, in Barcelona, the singer revealed that she had changed her mind a little bit. Now, she wasn't scheduled to release another 6-track EP but a full album. She announced the album's name, "Spoiler" and hinted the release date of the album; she said that it would be released by the beginning of summer. In April 2019 she collaborated with Morat in "Presiento". In May she collaborated with former One Direction member Zayn in the revamped version of "A Whole New World" for the live action film of Disney's "Aladdin". On May 17, 2019, she released "Nada Sale Mal", the lead single of her upcoming debut studio album. It peaked at number 4 on the Spanish charts and has been certified Gold. The album was released digitally and physically on June 7, 2019. It debuted at the top of the charts, was certified Gold in its first week and scored a Latin Grammy nomination for Best Pop Vocal Album at the 2020 gala. Later that month, the collaboration with Lola Indigo "Me Quedo" was released as the album's second single. Thanks to this work, Aitana was nominated for Best New Artist at the 20th Annual Latin Grammy Awards, where she performed "Mi Persona Favorita" alongside Greeicy, Nella and Alejandro Sanz.
