The Miss USA beauty pageant has been held annually since 1952 to select the United States competitor in the Miss Universe contest. The Miss Universe Organization (owned by Donald Trump) operates both pageants (as well as Miss Teen USA) - Miss USA will broadcast live on NBC as well as Xbox Live.

The current Miss USA (Nana Meriwether) hails from Maryland - she took over the title after the original winner (Olivia Culpo from Rhode Island) won Miss Universe in 2012.

The Miss USA 2013 beauties have been participating in preliminary rounds all week. Before Sunday evening's show, 15 semi-finalists will be chosen to compete on the live broadcast (the preliminary contest was held last Saturday). Fans can vote for their favorites online on the Miss USA Facebook page or official website.
