AllDay Project (Korean:올데이 프로젝트, stylized in all caps or abbreviated to ADP) is a South Korean co-ed group formed and managed by The Black Label. The group consists of five members: Annie, Tarzzan, Bailey, Woochan, and Youngseo. They debuted on June 23, 2025, with the single album Famous.
Name
The name "AllDay" was chosen after American music producer Will.i.am of co-ed group Black Eyed Peas reportedly came up with the word upon seeing the five members. On June 22, 2025, AllDay Project announced the name of their official fan club as "Day One", symbolizing "the Day One fan" who will join the group from the beginning and continue with them on an infinite journey.
History
Pre-debut activities
In early 2024, leaked photos of The Black Label trainees went viral, featuring Ella Gross, Bailey Sok and Annie Moon, among others, causing speculation that they were preparing to debut, though only Gross was confirmed to be under the label. Bailey Sok was notable for her work as a choreographer, and Annie Moon was known for being the granddaughter of Shinsegae chairwoman Lee Myung-hee. Later that year, The Black Label debuted their first group, Meovv, which included only Gross in the line-up.
In 2023, Youngseo was a contestant on R U Next?, a competition show held by Belift Lab to determine the members of what would become Illit. Youngseo placed second, earning a spot in the group, though she departed from Illit and Belift Lab before they debuted. Woochan was also known for appearing on a competition show, having appeared on Show Me the Money 6 in 2017, when he was 12. He went on to train with Big Hit Music as a member of Trainee A, a project to determine a new boy group. Tarzzan had experience prior to AllDay Project as a model and modern dancer, appearing in the music videos for NewJeans's "Supernatural" and I-dle's "I Do".
