Dior removed its Vietnamese 'Friend of the House' after her candy-fraud arrest

Thùy Tiên won Miss Grand International 2021 and became a 'Friend of the House' for Dior in Vietnam, appearing in the house's posts and at its events. In parallel she held a 30 percent stake in Chị Em Rọt (CER), a company whose Kera vegetable candy she promoted on livestreams alongside two other Vietnamese internet celebrities, Hằng Du Mục and Quang Linh. The candy was marketed with the claim that one candy equaled a plate of vegetables — a claim the police and courts later found false.

On March 15, 2025, police opened an investigation and placed Thùy Tiên under an exit ban while a fellow Kera livestreamer faced questioning. On April 7, Dior quietly edited a March 5 post on its official Facebook page, removing her image and tagged name. On May 19, the Ministry of Public Security's C01 unit indicted her for deceiving customers under Article 198, Clause 2 of the Penal Code; Dior removed her images from its pages again the same week.

On November 19, 2025, the Ho Chi Minh City court sentenced her to two years in prison and a 50 million dong fine. The court found 129,617 boxes had been sold to 56,385 customers, bringing more than 17.5 billion dong in revenue and about 12.5 billion dong in illicit gains; lab tests showed the candy's fiber content was 0.935 percent against a claimed 28.13 percent of vegetable powder. CER was ordered to compensate the 22 victims identified in the investigation.
