In an Instagram Story on Tuesday, the Mexican titleholder said she had received many hostile messages aimed at her and her family after the crowning, The Straits Times newspaper said.

Bosch published screenshots of the messages and said they cannot affect her because her “values and self-esteem are strong”.

“What must be in a person’s heart to wish harm on someone they don’t even know?” she wrote in Spanish.

She said that while she may be able to handle such remarks, others could be harmed mentally and emotionally.

“Today, I want to raise my voice not as a beauty queen, but as a woman…In recent days, I’ve received insults, attacks and even death threats for one reason only: because I won,” she said.

“Although these attacks hurt, they don’t define me. What does define me is my strength, my integrity, and the love I have for my country and for the women around the world whom I represent,” she wrote.

Bosch said her win shows that women are resilient, capable, and strong.

“To all the women who feel fear today, who live violence, who have been silenced: I see you, I honour you, and I use my voice for you,” her post said.

She thanked supporters for their trust and said their encouragement helps her stay focused and move forward.

Bosch also said she will continue using her platform to advocate for women’s rights.

“There is much work to be done, and my commitment is, and will remain, to use this crown for good,” she concluded the post.

Bosch broke her silence as debate grew over claims she won because of her family background. According to UK-based magazine Hello!her father, Bernardo Bosch Hernandez, is an engineer with 27 years of experience at state-owned oil firm Petroleos Mexicanos (Pemex) and now serves as an advisor to the General Director of Pemex Exploration and Production.

After the crowning ceremony on Nov. 21, French-Lebanese musician Omar Harfouch, one of three judges who withdrew from scoring, said Bosco was a “fake” winner who benefited from her father’s business ties with Miss Universe Organization (MUO) president Raul Rocha, People magazine said.

Harfouch previously accused MUO of lacking transparency and forming an “impromptu jury” to pre-select the top 30 finalists prior to the competition. MUO has denied the claims but has not clarified the Bosch family’s connections with the pageant leadership.

Fátima Bosch was born in 2000 in Teapa, Tabasco, Mexico, and studied fashion design at Iberoamericana University. She said she was bullied as a child due to her dyslexia and attention deficit hyperactivity disorder.

During the competition, she drew attention for a clash with Miss Universe executive Nawat Itsaragrisil. In early November, he accused her of not promoting Thailand enough and ordered security to remove her from the room when she tried to respond.

Bosch told reporters backstage that Itsaragrisil called her “dumbhead.”

Itsaragrisil later denied this but apologized for his behavior. Mexico’s first female president, Claudia Sheinbaum, praised Bosch’s actions and said she appreciated that Bosch spoke out against injustice.

Miss Universe, first held in the U.S. in 1952, is one of the world’s most-watched beauty pageants, with its broadcasting rights bought by 165 countries and territories. This year’s competition, which started in early November, faced several controversies.

After the final, contestants from Curacao and Estonia criticized the pageant on social media that it discriminates and no longer empowers women. On Tuesday, fourth runner-up Olivia Yacé, representing Ivory Coast, renounced her continental title to pursue her own path.

The same day, MUO president Rocha said Yacé could not win because her country’s visa restrictions make international travel difficult while the pagent requires frequent overseas trips.

Comments online called his remark discriminatory toward contestants from smaller countries.

On Instagram, Miss Guadeloupe Ophély Mézino, said Rocha was “trying to find a racist excuse for the fact that [he] didn’t choose someone who was highly qualified for this job.”
