Newly crowned Miss Universe, Gabriela Isler of Venezuela, took up her duties in Moscow on Sunday, twirling in a jewel-studded swimming costume valued at US$1 million.
Isler, 25, spoke to reporters a day after winning the title at a glitzy ceremony at a Moscow concert hall, saying she had stayed up all night talking to friends and family on the phone.
"I feel very happy to share my first day as Miss Universe," Isler said. "I'm a simple girl. I am just come to have fun, to enjoy the moment - and here I am."
She said she felt "honoured" at becoming the seventh Venezuelan Miss Universe, triumphing over 85 other women at the first competition held in Russia in its 61-year history.
Isler wowed the judges including Aerosmith singer Steve Tyler with her appearances in a bikini and sparkly silver evening dress.
As the new face of an Italian lingerie company, she posed in a Moscow hotel in a white cut-away swimming costume featuring an emerald pendant and swirls of diamonds and rubies, with a fur boa wrapped around the hips.
"It's very simple but very elegant, so it's like me," she said.
