On March 13, the Miss Mississippi Teen USA and Miss Mississippi USA welcomed two new titleholders.
Each contestant will compete in three equal phases of preliminary competition: active wear/swimsuit, evening gown, and interview. The scores from the preliminary phases of competition are added up, and the contestants with the highest composite scores become semifinalists. The number of semifinalists will be between 10 and 15, and will be determined by the total number of contestants in the competition.
Miss Mississippi USA 2021 is Bailey Anderson and Miss Mississippi Teen USA 2021 is Mattie Grace Morris!
