ICHILLIN’ is a seven-member girl group under KM Entertainment, based in South Korea. The group debuted on September 8, 2021 with the digital single GOT’YA. Its current lineup is E.JI, JIYOON, JACKIE, JOONIE, CHAERIN, YEJU and CHOWON, with Korean and American members working together as one team.

The name combines Aisling, associated with dreams and visions, with “chillin’.” Fans are known as WILLING. The official role lineup brings together E.JI’s leadership, two main vocalists, a main rapper and a dance line with distinct main- and lead-dancer positions.

The debut single and first mini album belong to different stages of the discography. Bridge of Dreams followed in 2022; I’m On It! arrived in 2023, Feelin’ Hot in 2024 and WILD CHERRY in July 2025. WILD CHERRY is the fourth mini album, not the debut album. Its title track XL (Extra Love) sits alongside Appetizer and Glass Heart.

The lineup changed in 2022 when SOHEE departed and JIYOON joined for Draw (MY TIME). The group later took part in the KPOP Breakout North American tour and continued connecting with Japanese audiences.

September 2026 introduced ICHILLIN’ J, a unit of E.JI, JOONIE and YEJU, with Look At Me and its title track BANANA. That three-member project is presented separately from full-group releases.
