Jung Kook Gets Emotional Birthday Serenade From BTS Bandmates & ARMY at ARIRANG Tour Concert

Jung Kook is 29! And to celebrate, the BTS star’s bandmates — plus tens of thousands of ARMY — serenaded him on stage during the group’s first night in Los Angeles on the Arirang World Tour.

In a clip captured by Billboard during the Tuesday (Sept. 1) show, Jung Kook looks on in wonder as the crowd at SoFi Stadium in Inglewood, Calif., belt out “Happy Birthday” in unison with some of the members. Toward the end of the song, Jin presents the man of honor with a special birthday crown.

“Thank you!” Jung Kook says humbly after the sweet display.

BTS has three more shows planned for SoFi over the next few days, after which the septet — which also includes Jimin, SUGA, j-hope, V and RM — will make stops in Latin America, Asia and Australia. The trek is scheduled to last through the middle of March and supports the group’s 2026 album, ARIRANG, which spent three weeks at No. 1 on the Billboard 200 and produced Billboard Hot 100-topping single “SWIM.”

For his part, Jung Kook has a lot to be proud of when it comes to his 28th year. In addition to contributing to BTS’ comeback over the course of 2026, he developed his partnership with Calvin Klein, helping to design his first clothing line with thoughtful pieces this spring. He also reunited with Jimin for the second season of their travel series, Are You Sure?!, visiting Switzerland and Vietnam on the heels of being discharged from the South Korean military.
