AllDay Project

ALLDAY PROJECT, also known as ADP, is a South Korean co-ed group managed by The Black Label. The group consists of five members: Annie, Tarzzan, Bailey, Woochan, and Youngseo. They officially debuted on June 23, 2025, with the single album “Famous.” Their debut was preceded by the release of the music video for “Famous” on June 16, 2025. The group quickly achieved recognition, securing their first music broadcast trophy on M Countdown with “Famous” within 10 days of their debut on July 3, 2025. The name “AllDay” was reportedly suggested by American music producer Will.i.am, signifying a project designed to transcend temporary trends and establish new ones. Their official fan club, “Day One,” was announced on June 22, 2025, to symbolize a lasting journey with their supporters.

The members brought prior experience to the group. Annie Moon, the granddaughter of Shinsegae chairwoman Lee Myung-hee, was part of MEOVV’s pre-debut lineup and is a Columbia University student. Tarzzan, a model and modern dancer, had appeared in music videos for NewJeans and (G)I-DLE. Bailey Sok is a choreographer who worked on K/DA’s “POP/STARS” and participated in “World of Dance 4.” Woochan was a contestant on “Show Me the Money 6” at age 12 and was a trainee under Big Hit Music. Youngseo competed in the survival show “R U Next?” and was in the original lineup for ILLIT before joining ALLDAY PROJECT. These varied backgrounds contributed to the group’s early activities and performances, culminating in their debut single album, which also included the track “Wicked.”
