Meet NewJeans Members: Exploring the Age Profiles of the Girl Group

NewJeans is a celebrated South Korean girl group formed by ADOR, a HYBE subsidiary, celebrated for its fresh sound and youthful charm.

They made an unexpected debut on July 22, 2022, with the single Attention, and quickly gained recognition with hits like Hype Boy and Ditto. The five-member group—Minji, Hanni, Danielle, Haerin, and Hyein—blends R&B-infused pop with nostalgic ’90s and 2000s influences, earning global acclaim and breaking records on charts like the Billboard Hot 100.

The members range in age from 16 to 20 and above. Following a hiatus in 2024 and controversies surrounding ADOR, they rebranded as NJZ in November 2024 and are preparing for a world tour this year.

NewJeans has charmed fans with their timeless style, dynamic energy, and approachable, girl-next-door appeal. Its name reflects both a fresh start—“new genes”—and the enduring popularity of denim, symbolizing its lasting impact across generations.
