Miss USA 2012 will air tonight from the Planet Hollywood casino in Las Vegas, featuring 51 pageant queens in swimsuits and evening gowns competing for one crown.

Giuliana Rancic, co-anchor of "E!News" and Andy Cohe, from "Watch What Happens: Live" will host the competition.

Throughout the Miss USA competition, each contestant representing the 50 United States and the District of Columbia competes in three categories: swimsuit, evening gown and interview. The telecast concludes with Miss USA 2011, Alyssa Campanella, crowning her successor.

The winner will represent the United States at the 61st Miss Universe pageant.

Last year, NBC’s Sunday telecast of the Miss USA was #1 for the night and matched the event’s highest adult 18-49 rating in six years and generated its biggest overall audience in four years, according to Nielsen Media Research.
