Lopes is Angola's first winner. She beat out 88 other competitors to win the title during the 60th anniversary of the world's biggest beauty pageant. Responding to questions, Lopes said that she has never had cosmetic surgery of any kind and that her three tips for beauty were to get a lot of sleep, use sun block even when it's not sunny and to drink lots of water. She said her smile was her best weapon in the competition.
The first runner-up was 23-year-old Olesia Stefanko of Ukraine and the second runner-up was Priscila Machado of Brazil. The third was Miss Philippines and the fourth Miss China.
Contestants spent the past three weeks in Sao Paulo, trying to learn samba dance steps, visiting impoverished children and kicking a football around for cameras as the Miss Universe pageant came to Brazil for the first time.
Despite battling against a home country favorite, Lopes won over the audience, speaking in the shared language of Portuguese. Angola, like Brazil, is a former Portuguese colony.
"She captivated the crowd and we were all behind her," said Brazilian Natalie Bursztyn, 20, who was in the crowd inside Credicard Hall where the event took place. "It was great that the judges also saw what the fans saw and gave her the crown. Her dress was beautiful and she knew exactly what to say when they asked her the question about her looks."
Speaking in a timid voice early Tuesday shortly after taking the crown in South America's largest city, the 25-year-old Lopes said that "as Miss Angola I've already done a lot to help my people."
