Miss Rhode Island, Olivia Culpo, won the title of Miss USA 2012 on Sunday night, beating a field of 50 high-heeled contestants at the pageant held in Las Vegas.
Wearing a purple, flowing gown, the 20-year-old Boston University sophomore looked at ease in the final rounds of competition, dancing alongside singer Akon during his live performance with the five finalists.
A cellist for 13 years, Culpo emphasized the importance of music education. She has performed at Boston Symphony Hall and Carnegie Hall in New York City.
The first runner-up was Miss Maryland, Nana Meriwhether. The remaining three finalists were Miss Ohio, Audrey Bolte; Miss Nevada, Jade Kelsall; and Miss Georgia, Jasmyn "Jazz" Wilkins.
