About
UDTT (우당탕탕 소녀단, short for Uddang Tangtang Girls) are a five-member South Korean girl group from TT Music. The group consists of leader Risako, Han Chaehee, Koo Hanna, Woo Jeong, and Kwon Yejin. Their official YouTube channel, @udtt_official, is the channel for UDTT (우당탕탕 소녀단). After introducing themselves with the pre-debut single “RETRY” in December 2024, UDTT officially debuted on April 29, 2025 with their first single album, School Rush. Its title track “REALLY REALLY” placed an upbeat deep-house pop sound around the flutter of first love, establishing the group’s youthful school-era opening. UDTT returned in June 2026 with their second single album, VIPER. The title track shifts toward a weightier bass line, an addictive dance-pop hook, and sharper group choreography, while the accompanying “Drift away” foregrounds more dreamlike vocals and high notes. The group’s current five-member lineup brings together performers previously seen on audition programs including Girls Planet 999, My Teenage Girl, and Universe Ticket.
