Five Korean celebrities face explosive controversies in 2026

South Korea’s entertainment industry has witnessed several high-profile controversies in 2026, with popular actors and K-pop idols facing allegations ranging from tax-related disputes to inappropriate conduct and historical family ties.

The incidents have sparked widespread online debate, raised questions about celebrity accountability and, in some cases, affected the careers of the stars involved.

ASTRO star and actor Cha Eun-woo faced allegations of tax evasion involving more than 20 billion won, reportedly equivalent to $13.6 million. The case centred on questions about whether a family-managed corporation had been used to obtain tax advantages on his entertainment earnings. Several brands reportedly ended their associations with the star. He paid the assessed tax amount by August, while his legal representatives challenged the assessment through a Tax Tribunal petition.

Former NCT member Mark Lee attracted criticism after being photographed wearing a T-shirt featuring the Confederate flag at a fan event in June. The symbol is widely associated with racism and white supremacy in the United States. Following the backlash, his label, Upper Room, accepted responsibility for the incident and explained that the shirt had been selected as a vintage fashion item.

Gunil’s exit from Xdinary Heroes followed an online controversy involving allegations made by an anonymous individual claiming to be his former girlfriend. She reportedly accused him of making insulting remarks about fans who had criticised the band’s concerts. His departure surprised fans, some of whom questioned JYP Entertainment’s decision amid the controversy.

Actress Ahn Ha-young faced criticism after discussing her family’s medical background on the television programme Problem Child in House. Her great-grandfather, Ahn Sang-ho, was reportedly linked to an organisation whose leadership included figures associated with Japan’s colonial administration in Korea. The revelations triggered debate over her family’s historical connections during Japan’s colonial rule of Korea from 1910 to 1945.

Rising actor Hong Min-gi became the subject of serious allegations in August after a woman claiming to be his former girlfriend accused him of dating violence and mistreating animals. Her social media posts also alleged verbal abuse, controlling behaviour, privacy violations and sexual misconduct. The claims generated widespread discussion online. The allegations remain claims attributed to the accuser and should not be treated as established facts without independent verification.
