KATSEYE member Manon has found herself at the center of online controversy after a viral photo from the group’s Coachella performance sparked widespread speculation and drug-related allegations.

The incident occurred during KATSEYE’s set at the Coachella Valley Music and Arts Festival in April 2026. A photograph showing Manon with visibly dilated pupils quickly spread across social media platforms, leading some users to accuse the 18-year-old singer of being under the influence of drugs. The image was captured during one of the group’s high-energy performances, and within hours it had been shared thousands of times with comments questioning her condition.

The backlash intensified when netizens began comparing the photo with previous images of Manon, claiming her eyes looked unusually large and glassy. Some users went as far as to label her a “bad influence” on the group and called for her removal from KATSEYE. Others defended the young performer, pointing out that dilated pupils can result from many innocent factors, including bright stage lights, camera flashes, fatigue from intense rehearsals, or even contact lenses.

Manon has not yet issued a direct response to the allegations. However, her fellow KATSEYE members and the group’s agency, HYBE x Geffen, have remained silent on the matter so far. The lack of an official statement has only fueled further speculation and debate across online communities.

This is not the first time KATSEYE has faced scrutiny since their debut. As a global girl group formed through the survival show “The Debut: Dream Academy,” the members have been under intense public observation from the beginning. Manon, who is of Swiss-Haitian descent, has often been praised for her unique visuals and powerful stage presence, but she has also been the target of unfair criticism and body-shaming comments in the past.

Many fans and supporters have pushed back against the drug allegations, calling them baseless and harmful. They argue that judging someone’s state based on a single photo taken under festival lighting is irresponsible and unfair. Some pointed out that dilated pupils are a common occurrence during live performances due to adrenaline, stage lights, and the physical demands of dancing and singing simultaneously.

Others have expressed concern about the speed at which rumors spread online and how quickly young idols are subjected to harsh judgment without evidence. The incident has sparked broader conversations about the pressures faced by rookie idols, especially those performing at major international festivals like Coachella, where every movement is scrutinized by millions.

KATSEYE performed as part of Coachella’s stacked lineup, marking one of their biggest career moments to date. Their energetic set received generally positive reviews from critics and fans who attended, with many praising the group’s tight choreography, vocal delivery, and stage charisma. The controversy surrounding Manon’s photo has unfortunately overshadowed some of the positive coverage of their performance.

As of now, neither Manon nor the group’s agency has commented publicly on the viral photo or the resulting allegations. Supporters are hoping for a swift and clear response to put an end to the speculation and allow the members to focus on their music and upcoming activities.

This episode once again highlights the double-edged sword of social media fame. While platforms allow artists to connect directly with fans, they also create an environment where unverified claims can spread rapidly and cause significant emotional distress to young performers.

Manon and KATSEYE are still in the early stages of their careers, and many hope this incident will not overshadow their hard work and growing achievements in the global music scene.
