When asked how she felt about winning the crown, she said, "Ask me after I've had a pizza."
Fakih nearly fell while finishing her walk in a long, strapless gown because of the length of its train, but she made it without a spill and went on to win.
During the interview portion, Fakih was asked whether she thought birth control should be paid for by health insurance, and she said she believed it should because it's costly.
"I believe that birth control is just like every other medication even though it's a controlled substance," Fakih said.
Fakih replaces Miss USA 2009 Kristen Dalton and won a spot representing the United States in the 2010 Miss Universe pageant. She also gets a one-year lease in a New York apartment with living expenses, an undisclosed salary, and various health, professional and beauty services.
Miss Oklahoma USA Morgan Elizabeth Woolard was named first runner-up after handling a question about Arizona's new immigration law. Woolard said she supports the law, which requires police enforcing another law to verify a person's immigration status if there's "reasonable suspicion" that the person is in the country illegally.
She said she's against illegal immigration but is also against racial profiling.
"I'm a huge believer in states' rights. I think that's what's so wonderful about America. So I think it's perfectly fine for Arizona to create that law."
"The Office" actor Oscar Nunez was booed as he asked the question and asked the audience to wait until he finished the question before they reacted.
Miss Virginia USA Samantha Evelyn Casey was the second runner-up, Miss Colorado USA Jessica Hartman was third runner-up, and Miss Maine USA Katherine Ashley Whittier was the fourth runner-up.

After 15 contestants strutted in swimsuits, five were eliminated. Another five were eliminated after the evening gown competition.
