K.O. is Danna's sixth studio album, released on January 13, 2021 through Universal Music Mexico. The title is short for "knockout" — as Danna explained: "With this album, I knocked out all of the bad stuff that was killing me, emotionally. I used it to drain everything I had in my heart." A bold, cathartic pop record, K.O. earned a Latin Grammy nomination for Best Pop Vocal Album and spawned eight singles including No Bailes Sola (with Sebastián Yatra), Friend de Semana (with Luísa Sonza and Aitana), and the award-winning Calla Tú.
