Miss Universe Canada officials have banned 23-year-old transsexual Jenna Talackova, who was born a boy, from competing in the pageant finals to be held in Toronto, Canada in May, 2012.
Talackova, from Vancouver, was one of sixty-five women chosen to compete in the contest, which is owned by Donald Trump.
The Daily Mail reports that Denis Davila, national director of Miss Universe Canada, said every contestant must be a "naturally born female."
Talackova felt that she was a girl by age four, started hormone therapy at fourteen and had sex reassignment surgery at nineteen.
She's previously competed in both transsexual and women's beauty pageants.
Talackova told the National Post: "All I can say is that they disqualified me because I'm not 'natural born.' [That] doesn't make sense because since I was conscious, I always felt this way."
After being kicked out of the pageant, Talackova tweeted: "I'm disqualified, however I'm not giving up. I'm not going to just let them disqualify me over discrimination."
Online support for Talackova is growing. People have started a petition, on Change.org, demanding that she be allowed to compete.
