Mexican model Rivera died Feb. 5, but her death only emerged this week. In 2004, the then-21-year-old Rivera starred in the British Sky reality show There's Something About Miriam, which had six young men competing to win her heart without knowing she was transgender. She revealed she was transgender after selecting the winner. Rivera also guest-starred on Big Brother Australia. There's Something About Miriam was so controversial that Sky essentially disowned it.
