MANILA - Catriona Gray's home province of Albay is proud of her, its Congress representative said Monday, crediting her birthplace in Bicol region as a factor in her victory in this year's Miss Universe tilt.

The 24-year-old Gray won the Philippines its fourth Miss Universe crown in a red gown designed by Mak Tumang to pay homage to Albay's active Mayon Volcano.

"Truly an Albayana, she was the most prepared candidate ever -- if you prepare to fight calamities, the more you are prepared for victory," Albay Rep. Joey Salceda said in a statement.

"She is beautiful, truly Daragang Mayon. The entire Albay is happy and proud of her achievement as proud [as] she is of her roots," he added.

Gray, famous for her slow motion twirl, showcased other nationalist apparel in the pageant, including a long gown that symbolized the mythical ibong adarna, a T’boli headdress, and a bodysuit with intricate Pintados pattern and a giant lantern strapped to the back.

The Filipina-Australian beauty also highlighted her advocacy for educating underprivileged children in depressed areas.

Vice President Leni Robredo, who also hails from Bicol, said Gray's victory "brought happiness to millions of households throughout our nation."

"Regardless of different backgrounds and allegiances, in this, you have brought us together," she added.

"With the eyes of the world and the entire Filipino nation on you, you chose to highlight your work with the poor, and to send a much-needed message of hope to all. With those inspiring words, you already became a winner in my heart, and, I am certain, in those of many others."

The Vice President also urged Gray to "make full use of your new role as an ambassador to continue bringing the message of hope to the world."
