The image, originally shared after Tien’s appearance at Dior’s Paris Fashion Week show on March 5, was removed on Monday, shortly after her official association with the brand began.

Ngoi Sao Newspaper reached out to representatives from Dior Vietnam, but the brand has not commented on the removal of Tien’s images.

The move comes amid Tien’s ongoing controversy over alleged false advertising. In Dec. 2024, she announced a collaboration with online influencers Pham Quang Linh and Nguyen Thi Thai Hang to launch Kera Supergreens Gummies, a fiber supplement. Tien promoted the product on her Facebook page, which has over 2.6 million followers, claiming that "a gummy contains a dish’s worth of vegetables," positioning it as a nutritious snack for both children and adults.

However, a consumer later found discrepancies between the advertised ingredients and the actual content of the product after testing it at the Quality Assurance and Testing Center 2. The results revealed that the entire 30-gummy box contained only 0.51 grams of fiber, much less than advertised, sparking public backlash. In response, Tien removed the related posts from her Facebook page.

The Ho Chi Minh City Food Safety Department later released the results of a product test for Kera Supergreens Gummies, conducted at the request of the Ministry of Health’s Food Safety Department. The test confirmed that the levels of sugar, protein, fat, and energy content were consistent with the product’s official self-declaration, but the packaging failed to mention fiber content, despite marketing the product as a fiber supplement. Authorities ruled out that the product was "counterfeit."

Following the investigation, Tien, Linh, and Hang were summoned for questioning, where they admitted to providing inaccurate information about the product. Linh and Hang were each fined VND140 million (US$5,426) for misleading advertising, while Tien was fined VND25 million for failing to disclose that her social media posts about the product were sponsored, violating advertising regulations.

The Dak Lak Provincial Police then announced that Tien has been temporarily banned from leaving Vietnam from March 15 to May 15 as part of the ongoing investigation.

At 26, Tien made history as the first Vietnamese contestant to win the Miss Grand International title.
