Allegations Against BLACKPINK Jisoo’s Brother Spark Controversy

On May 29, 2025, a disturbing accusation surfaced on the anonymous employee community platform Blind, alleging that the older brother of BLACKPINK’s Jisoo, identified as Mr. Kim, secretly recorded a sexual encounter without consent. The post, titled “I was illegally filmed by BLACKPINK Jisoo’s brother,” was shared by an anonymous individual who claimed to have been in a sexual relationship with Mr. Kim at his home. The accuser stated that they later discovered the act had been recorded using a hidden camera, adding that Mr. Kim allegedly shared the footage with acquaintances and boasted about possessing similar recordings of other women. The post also claimed that Mr. Kim was involved with multiple women simultaneously, including one relationship during his wife’s pregnancy.

The original post was removed shortly after being uploaded, but its contents spread rapidly across social media, drawing significant attention. Mr. Kim, who heads Biomom, a company known for children’s health supplements, and recently launched an entertainment venture called Blissoo with Jisoo as its ambassador, is closely tied to his sister’s professional endeavors. Jisoo’s agency, Blissoo, responded to the allegations with a brief statement to Korean media, saying, “We are currently checking the facts.” No further comments have been issued by the agency at this time.

The controversy has raised concerns among fans and the public, particularly given Jisoo’s association with her brother’s business ventures. As the situation develops, the allegations continue to fuel discussions online.
