The much-anticipated performance of the acclaimed K-pop group MONSTA X at the 2025 iHeartRadio Jingle Ball Tour in New York proceeded with a notable absence, as member Kihyun was unable to join his bandmates on stage.
The announcement was made by the group’s agency, STARSHIP Entertainment, on December 12, local time, just ahead of the New York concert.
This sudden withdrawal was due to a severe health issue that required immediate medical attention and subsequent rest, disappointing fans who were eager to see the full group perform at one of the biggest holiday music events in the United States.
The agency’s prompt communication aimed to reassure fans while prioritizing the health and stability of the main vocalist.
Diagnosis and Need for Rest
According to the official statement released by STARSHIP Entertainment, Kihyun experienced a worsening of his health while in the United States for the tour. This deterioration necessitated an urgent visit to a local hospital.

Following a thorough examination, medical professionals diagnosed the powerful vocalist with acute gastroenteritis.
This common but debilitating condition, which involves inflammation of the stomach and intestines, typically causes severe discomfort, dehydration, and a need for immediate and comprehensive rest.
The doctor’s firm opinion was that Kihyun required “plenty of rest and stability” to recover fully.

In light of the medical advice, the agency made the difficult but necessary decision to prevent Kihyun from participating in the New York leg of the Jingle Ball Tour.
The statement explicitly cited the doctor’s recommendation and the current state of Kihyun’s health as the determining factors, underscoring the impossibility of him proceeding with the rigorous demands of a concert performance.
This move highlights the music industry’s growing commitment to prioritizing artist well-being, even when faced with major international commitments and fan expectations.
The physical intensity and high-energy demands of a MONSTA X performance would have been incompatible with the severity of his diagnosis, making withdrawal the safest choice for his long-term health.
Message to Monbebe and Commitment to Recovery
STARSHIP Entertainment dedicated a significant portion of their statement to the group’s loyal fanbase, known as Monbebe.

Recognizing the disappointment that fans felt after looking forward to the group’s highly anticipated appearance, the agency offered a sincere apology:
“We sincerely apologize to the fans who waited for a long time. We ask for fans’ generous understanding.”
The agency’s focus then shifted to a firm commitment to the idol’s recovery, promising to “do its utmost to help Kihyun recover as quickly as possible and meet his fans again in better health.”
This promise is crucial, as the group is known for their strong bond with their Monbebe, and transparency about his condition helps manage expectations and direct fan energy toward supporting his healing process.
The absence of one of the group’s core members, especially its main vocalist, undoubtedly changes the dynamic of their high-octane setlist.
Despite this, the remaining members of MONSTA X demonstrated their professionalism and dedication by performing as scheduled, ensuring that the show went on for the fans in attendance, even with Kihyun cheering them on from the sidelines during his recovery period.
Impact on the Remaining Tour Schedule
The Jingle Ball Tour is a multi-city event that places demanding travel and performance schedules on participating artists.
Following the New York performance on December 12, MONSTA X’s schedule includes several other major stops across the United States in the coming days.
The group is slated to perform at:
- Philadelphia on December 15.
- Washington, DC on December 16.
- Miami on December 20.
While the New York concert was confirmed to be without Kihyun, the agency’s priority remains his swift and complete recovery.
His participation in the subsequent dates will be dependent on his health improvement and further guidance from medical professionals.
Fans across the East Coast cities are now anxiously awaiting updates on his condition, hoping he will regain enough strength to rejoin his bandmates for the remaining legs of the prestigious holiday tour.
The temporary absence serves as a reminder of the physical sacrifices and challenges K-pop idols endure while maintaining packed international schedules.
