WATERBOMB also shared another performance clip alongside a playful caption referencing BIBI’s hit song BIBI Vengeance. “Kim Hyung Seo, bad girl? No, she’s absolutely crazy—in the best way possible! WATERBOMB is insanely fun. Everyone, go crazy!” The video captured BIBI delivering a powerful performance that energized the crowd.

Fans quickly flooded social media with praise, applauding her confident stage presence, charismatic performance, and ability to command the audience. Many even joked that BIBI had officially claimed the title of this year’s “WATERBOMB goddess,” a nickname often associated with other popular performers at the annual summer festival.

Meanwhile, BIBI released her new song “BUMPA” on May 20. The track marked her first new music in a year following her second full-length album EVE:ROMANCE, which was released in May 2025. The title “BUMPA” comes from a Jamaican slang term referring to one’s hips or backside, symbolizing the freedom of dancing and enjoying the moment. BIBI personally participated in writing and composing the song, further showcasing her artistic identity as a singer-songwriter.
