Shinsegae Chaebol Moon Seo-yoon Not a Member of Teddy’s Girl Group: Confirmed Another Debut Under THE BLACK LABEL!
According to the music industry on May 10th, Moon Seo-yoon was not part of “Teddy’s girl group” scheduled to debut in the first half of the year. Earlier this year, Moon Seo-yoon attracted attention when she appeared in a photo of trainees from The Black Label‘s girl group, sparking speculation about her potential debut with “Teddy’s girl group”.
Although Moon Seo-yoon was not part of “Teddy’s girl group” set to debut in the first half of the year, continued public interest is expected regarding her potential debut, given her past status as a trainee under The Black Label.
In February, several online communities posted a photo of trainees from The Black Label under the nickname “Teddy’s girl group”. Moon Seo-yoon was also featured in the photo, raising expectations.
Among the trainees featured in the photo was American child actress Ella Gross, who signed an exclusive contract with The Black Label in 2018. At the time, The Black Label stated, “The girl group being produced by The Black Label is preparing for their debut in the first half of this year. Specific details will be announced later.”
It turned out that the new Teddy’s girl group is MEOVV and Moon Seo-yoon will debut later (still under THE BLACK LABEL)!
In 2025, Moon Seo-yoon is confirmed to make her debut as a K-pop idol under THE BLACK LABEL, a music label founded and led by producer Teddy. The announcement was made public on June 9, 2025 through THE BLACK LABEL’s official social media platforms.
The new idol group, titled ALLDAY Project, will debut as a co-ed ensemble, featuring both male and female members. The lineup includes Youngseo, an ex-member of HYBE’s girl group ILLIT, rapper Jo Woo-chan (formerly of BIGHIT and known from Show Me the Money 6), renowned dancer Bailey Sok, model Lee Chae-won, and Moon Seo-yoon herself.
