However, her photo has yet to be restored on Dior’s official Instagram account.

Star of Newspaper contacted Dior Vietnam for comment, but the brand has yet to respond regarding the reappearance of Tien’s photo.

On April 7, social media users noted that Tien’s photo had been removed from Dior’s social media accounts. The removal came shortly after she became embroiled in a public backlash over misleading promotional claims for a dietary supplement.

Dior’s removal of Tien’s photos came amid her controversy involving alleged false advertising. In Dec. 2024, she announced a collaboration with online influencers Pham Quang Linh and Nguyen Thi Thai Hang to promote Kera Supergreens Gummies, a fiber supplement. On her Facebook page—followed by over 2.6 million people—Tien claimed that “a gummy contains a dish’s worth of vegetables,” marketing it as a nutritious snack suitable for both children and adults.

However, the product faced backlash after a consumer sent it to Quality Assurance and Testing Center 2 for analysis. The results revealed that an entire box of 30 gummies contained just 0.51 grams of fiber—far below the claims—prompting public criticism. Tien later removed the promotional posts from her Facebook page.

Subsequent testing by the Ho Chi Minh City Food Safety Department, at the request of the Ministry of Health, found that the supplement’s sugar, protein, fat, and energy levels matched its self-declared specifications. However, the packaging failed to list any fiber content, despite being marketed as a fiber-rich product. Authorities determined the product was “counterfeit.”

Tien, Linh, and Hang were then summoned for questioning and admitted to promoting the product with inaccurate information. Linh and Hang were fined VND140 million (US$5,384) each for misleading advertising, while Tien was fined VND25 million for failing to disclose that her promotional posts were sponsored—violating advertising regulations.

The Dak Lak Provincial Police later issued a temporary travel ban on Tien, barring her from leaving Vietnam between March 15 and May 15 as the investigation continues.

At age 26, Tien became the first Vietnamese contestant to win the Miss Grand International title.
