Teddy Park has been a force in the K-pop industry for nearly 30 years, first making his mark as a member of YG Entertainment’s 90s hip-hop group 1TYM. He later rose to become YG’s head producer, crafting iconic hits for 2NE1 and BLACKPINK before launching his own YG-affiliated label, THEBLACKLABEL. Now, following the introduction of MEOVV, Teddy is preparing to debut THEBLACKLABEL’s first-ever co-ed group: ALLDAY PROJECT. Comprised of five members, the group will officially debut on June 23, 2025, with their single album “Famous.” ALLDAY PROJECT is already generating buzz for its standout lineup, which includes former pre-debut idols, elite dancers, and even a chaebol heir. True to their name, the group aims to deliver a timeless concept, not just another fleeting trend.
Let’s meet the five dynamic members of ALLDAY PROJECT:
