Matt Bomer is the latest celebrity to express support for Wentworth Miller, who recently came out as gay.

Bomer praised the 'Prison Break' actor for his decision, which was one he made after he was invited to a Russian film festival. "Wow, I think it's really bold and incredibly classy how he came out and did it," Bomer told E! News. "I am really proud of him. It's very reflective of his amazing character." 

The 35-year-old 'White Collar' actor also commented on the LGBT-positive legal changes occurring in the U.S. Currently, 13 U.S. states and the District of Columbia have legalized same-sex marriage. "I hope all these laws continue to pass but we still have a long way to go," he said. 

Bomer came out as a gay man in February 2012, while accepting an award at a Desert AIDS Project event.

Miller's decision to come out was presumably sparked by the Russian government's enforcement of anti-gay laws. "Thank you for your kind invitation. As someone who has enjoyed visiting Russia in the past and can also claim a degree of Russian ancestry, it would make me happy to say yes," Miller, 41, wrote in a letter to Maria Averbakh, directer of the St. Petersburg International Film Festival. "However, as a gay man, I must decline."

"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," he wrote.

The letter was posted on the GLAAD website.

Bomer isn't the first celebrity to express support for Miller. Many celebrities took to Twitter to praise his decision.

"I'm proud of Wentworth Miller for speaking out in support of equality. Russia doesn't know what they're missing," comedian Ellen DeGeneres tweeted. 

'Modern Family' actor Jesse Tyler Ferguson also tweeted support: "So proud of #WentworthMiller. Coming out can be hard and scary but coming out to send a message of tolerance is heroic."
