Every woman worries about tripping wearing heels, and Miss USA had on a 4-inch mega heel that could be the culprit, she said.
"I think my heel got caught in the lining of my dress and whenever it hit the slippery stage, down I went for the count," she told The Early Show co-anchor Hannah Storm. "You know? But hey, I did it with style. I had my nice little Cavalli gown on."
During the pageant, when Smith was chosen to stay in the final five and Miss Mexico was eliminated, the crowd again erupted into boos, so much so that co-host Mario Lopez told them to quiet down. Owner of the pageant Donald Trump said he was worried the audience might storm the stage.
"I think there were just a myriad of reasons why," Smith said. "I mean, I can't pinpoint. It's only speculation. It could have been political reasons. It could have been athletic rivalry. It could have been the fact that their girl didn't make it to the top five. But I can't dwell on it. I was there to compete and did just that. I had to represent my country to best of my ability regardless of the situation. I think I was able to — to hold my own."
Now Smith is moving on to her work as Miss USA. She said she is championing breast and ovarian cancer awareness and will be off to Kenya in a week.
"It's going to be an exciting year," she said. "I can't wait to see what's in store."
