Luke Macfarlane, who plays a gay man on "Brothers & Sisters," has confirmed that he's actually gay in real life.

The Canadian actor officially went public with his sexual orientation in an interview in Canada's Globe and Mail on Tuesday (April 15).

Coming out in Hollywood was not an easy decision, considering that it may affect his career.

"I don't know what will happen professionally ... that is the fear, but I guess I can't really be concerned about what will happen, because it's my truth," says Macfarlane, 28. "There is this desire in L.A. to wonder who you are and what's been blaring for me for the last three years is how can I be most authentic to myself -- so this is the first time I am speaking about it in this way."

Despite going public, Macfarlane refuses to discuss his personal life, but admits he'd like to be married someday. He'll get a chance to feel what it's like on the "Brothers & Sisters" season finale when his character Scotty Wandell weds his partner Kevin Walker (Matthew Rhys).

"How exciting that we're saying, 'This can be part of the cultural fabric, now,' because it is two series regulars, two people that you invite into your home and you see every week," he says. "It's telling of the beginning of more waves and I'm very proud of that.

"Most importantly, in portraying gay people, the more we realize it's just like portraying anybody else<" he adds. "Gay marriage, it's not about two people being gay, it's about two people who love each other and who have decided to commit to each other for the exact same reasons any other couple would get married."

The episode will air on ABC on May 11.
