Philippines' Catriona Elisa Gray wins Miss Universe 2018

Catriona Gray from the Philippines was crowned Miss Universe on Monday, the fourth time the Southeast Asian country has won the international beauty pageant.

"My heart is filled with so much gratitude. There were moments of doubt where I felt overwhelmed and I felt the pressure," said Gray, who wore a red and orange dress that was inspired by Mount Mayon, a volcano that erupted this year.

Gray is the fourth Filipina to win Miss Universe and the second in three years. The pageant was shown live on the country's biggest television network and dominated social media.

The Philippines previously won Miss Universe titles in 2015, 1973 and 1969.
