BIBI has once again become one of the most talked-about artists at Waterbomb Seoul 2026, but this time, the attention extends beyond her music.

Waterbomb Seoul 2026 took place on July 25 at the outdoor Global Stage at KINTEX in Goyang, Gyeonggi Province.

During her set, BIBI performed hit songs including “Bamyanggang” and “BIBI Vengeance (Bad B**)”, quickly earning praise as one of this year’s standout performers.

Midway through the show, BIBI, who initially appeared in a jumpsuit, dramatically unzipped and removed the outfit to reveal a bikini underneath. The costume change drew loud cheers from the crowd, but it was the choreography that followed that fueled controversy.

Surrounded by male dancers, BIBI knelt on stage while the dancers lowered a microphone toward her waist level, creating a sequence that many viewers interpreted as resembling a sexual act. Clips of the performance rapidly spread across social media, generating intense discussion.

Some viewers criticized the routine as inappropriate for a public performance, arguing that it crossed acceptable boundaries. Others defended the performance, saying it matched Waterbomb‘s bold identity and should be viewed as artistic entertainment intended for an adult audience.

This is not BIBI’s first controversial appearance at the festival. At Waterbomb 2022, she removed a white T-shirt during her performance. However, the string of her swimsuit unexpectedly came undone, nearly resulting in a wardrobe malfunction that could have exposed her chest. Fortunately, BIBI reacted quickly by covering herself while staff members rushed to assist, preventing a more serious incident.

BIBI is far from the only artist whose Waterbomb appearance has drawn scrutiny. Singer Kwon Eun Bi has repeatedly become a focal point of discussions surrounding revealing festival outfits.

At last year’s event, she performed in a white bikini layered with a red plaid cropped shirt, denim hot pants, and Western boots as part of a cowgirl-inspired concept. While many praised her confidence, critics argued that the styling excessively emphasized her figure. The debate intensified after promotional materials featuring photos from the performance were widely circulated.

A similar controversy emerged during Waterbomb 2023, when Kwon Eun Bi wore a bikini paired with a sheer cardigan. Although the outfit helped cement her reputation as one of Waterbomb‘s signature performers, many online discussions focused more on her appearance than on her performance of her hit song “Underwater,” disappointing some fans who felt her musical abilities were being overshadowed.

Each year, discussions surrounding Waterbomb often evolve into debates over gender-based double standards. Supporters point out that male performers such as Jay Park and Baekho have received widespread praise for appearing shirtless and showcasing muscular physiques during their Waterbomb performances. They argue that criticizing female performers like BIBI and Kwon Eun Bi for revealing outfits or provocative choreography while celebrating similar displays by male artists reflects inconsistent standards. Others counter that the issue is not the amount of skin shown but rather the increasingly explicit nature of certain stage performances.

Supporters also emphasize that Waterbomb is an adults-only festival, restricting admission to those aged 19 and older. They argue that audiences attend the event with the expectation of bold fashion, energetic performances, and a party atmosphere similar to international music festivals such as Coachella, where revealing outfits are commonplace among both performers and attendees.

As a result, many believe artists should have greater freedom to express themselves creatively within the festival’s adult-oriented setting.

Despite these arguments, critics maintain that artistic freedom and excessive sensationalism are not synonymous. They acknowledge that daring performances can energize audiences and contribute to the unique atmosphere of large-scale festivals. However, they argue that performances designed primarily to provoke sexual reactions risk shifting attention away from music itself.

The resulting online discourse often escalates beyond criticism of the performances, with explicit comments and objectifying remarks spreading rapidly across social media. In these situations, the issue extends beyond individual performers, affecting broader perceptions of both female and male artists.

The renewed controversy has also revived an ongoing conversation about Waterbomb‘s evolving identity. In the past, Kim Yoon Ah, vocalist of the rock band Jaurim, remarked that Waterbomb was “honestly not really a music festival,” suggesting that its atmosphere and spectacle had begun to overshadow the music itself.

Now celebrating more than a decade since its launch in 2015, Waterbomb continues to enjoy enormous popularity. Yet each year, debates over increasingly provocative performances raise the same question: Is Waterbomb still primarily a music festival, or has spectacle become its main attraction?

As the festival continues to grow, artists, organizers, and audiences alike may face increasing pressure to balance creative freedom with maintaining boundaries appropriate for a large public entertainment event.
