Beautiful Chaos is the second extended play (EP) by girl group Katseye. It was released on June 27, 2025, through Hybe UMG and Geffen Records. Its first single, "Gnarly", became the group's first entry on the Billboard Hot 100. The Latin-inspired "Gabriela" was released one week ahead of the EP's worldwide release date, and a final single, "Gameboy", was released concurrently with the EP. Upon its release, the EP entered weekly music charts in fourteen regions, including reaching the top ten in Belgium, South Korea, and the US. The entry in the US' Billboard 200 demonstrated the group's growth since their first EP, as it marked their first entry in the top ten of the chart.[2] To support the EP, Katseye embarked on their first concert tour, the Beautiful Chaos Tour, in November 2025. All songs from Beautiful Chaos are being performed on the tour.
