With her promotion, Miss Maryland Nana Meriwether becomes the new Miss USA.
The Miss Universe pageant was back in Las Vegas this year after being held in Sao Paulo in 2011. It aired live on NBC and was streamed to more than 100 countries.
The panel of 10 judges included singer Cee Lo Green, "Iron Chef" star Masaharu Morimoto and Pablo Sandoval of the San Francisco Giants.
Asked on the red carpet whether he found playing in the World Series or judging the beauty pageant to be more difficult, Sandoval said both were hard.
As Miss Universe, Culpo will receive an undisclosed salary, a wardrobe fit for a queen, a limitless supply of beauty products, and a luxury apartment in New York City.
