In a transcript of the email said to be from Mommim and provided by the Miss Universe Organization, the 27-year-old from Cranberry, Penn., wrote that she refused to be "part of a pageant system that has so far and so completely removed itself from its foundational principles as to allow and support natural born males to compete in it. This goes against ever moral fiber of my being. I believe in integrity, high moral character, and fair play, none of which are part of this system any longer."

Speaking of moral fiber, after Miss Universe Canada hopeful Jenna Talackova was initially barred from competition, the MUO officially altered its rule book in April to allow for transgender women like Talackova (she had gender-reassignment surgery at 19) to compete for the crown.

Talackova ultimately placed in the top 12 and shared the title of Miss Congeniality with three others.

Monnin, meanwhile, stands by her allegation that the Miss USA pageant was rigged. She wrote on Facebook that, when she found out that the finalists were predetermined, she "decided at that moment to distance myself from an organization who did not allow fair play and whose morals did not match my own."
