Miss South Africa was crowned Miss Universe on Sunday in Atlanta after a lavish ceremony filled with glitter and heartfelt speeches about female empowerment.

Zozibini Tunzi, 26, finished first ahead of the Puerto Rican and Mexican finalists in a flashy televised event, hosted by American comic turned TV personality Steve Harvey.

Tunzi earned cheers during her closing speech, a new segment of the competition, in which she talked about wanting to empower young women to feel confident.

"I grew up in a world where a woman who looks like me, with my kind of skin and my kind of hair, was never considered to be beautiful," she said.
