"I have no words. I am really happy," said the beauty queen, dressed in a white gown with a sheer top and strategically placed fabric flowers, upon receiving the glittering crown and being doused in silver confetti.
Aldorino, who succeeds Ksenia Sukhinova of Russia as Miss World, became a crowd favorite earlier in the competition when she won the swimsuit category.
Second place went to Perla Beltran Acosta, a 23-year-old engineering graduate from Mexico and third place went to hometown favorite, Tatum Keshwar, 25, of South Africa.
The winner, who we think is a dead ringer for Missoni heiress Margherita Missoni, has been working as an administrative clerk for the HR department of a hospital in Gibraltar, a British territory, for five years.
Now, with her new role as Miss World, the Spanish- and English-speaking Aldorino says: "My time has come. I am living a dream that I pray will never end."
The festive pageant in Johannesburg featured traditional Zulu dancers and a Bollywood star as a judge. At the end of the ceremony, a flag was handed off to officials from Vietnam, the site of nest year's 60th Annual Miss World contest.
