The 41-year-old model was invited to attend the upcoming Russian festival but he rejected the invitation as new Russian laws has banned "propaganda of nontraditional sexual relations around minors," so he wrote a letter to Maria Averbakh, director of the St. Petersburg International Film Festival saying he is a gay.
"As a gay man, I must decline," Miller wrote in a letter posted on GLAAD's website,. "I am deeply troubled by the current attitude toward and treatment of gay men and women by the Russian government. The situation is in no way acceptable, and I cannot in good conscience participate in a celebratory occasion hosted by a country where people like myself are being systematically denied their basic right to live and love openly."
