"Última" was initially announced on 29 February 2024, when Shakira shared the tracklist of her twelfth studio album Las Mujeres Ya No Lloran on her social media accounts.
[2][3][4] Shakira shared that creating the album was an "alchemical process" and that she "rebuilt herself" writing each song: "As I sang them, my tears were transformed into diamonds and my vulnerability into resilience".
[9] Based on the preview, Judith del Rio from La Vanguardia called the song "the final farewell to her great love".
[17] Lucas Villa from NME emphasized that "Shakira is one of Latin music’s most prolific and poetic songwriters, and she offers the most insight into her breakup with Piqué on the heartbreaking ballad", outlining how she "sounds like she’s on the verge of tears as she reflects on what went wrong" on the song.
