Tension got under the skin of Crystle Steward of Texas, the second Miss USA in a row to fall down during the Miss Universe pageant. She tripped on the train of her bejeweled evening gown as she made her entrance.

Like Smith, Stewart quickly stood up after her fall and continued on as if nothing had happened.
Stewart, 26, is a motivational speaker and former track and filed star who is working on a book called "Waiting to Win."
Her mishap occurred just after the judges had narrowed the field of 80 to the final 10: Miss USA, Miss Kosovo, Miss Australia, Miss Spain, Miss Mexico, Miss Colombia, Miss USA, Miss Dominican Republic, Miss Russia, Miss Italy and Miss Venezuela.
