We don't consider this anyone's business, but because Luke MacFarlane himself came out with the information in a recent interview with Canadian newspaper Globe and Mail, we assume the actor wants it to be publicized.

The Brothers & Sisters star is gay.

"I don't know what will happen professionally," MacFarlane said. "That is the fear, but I guess I can't really be concerned about what will happen, because it's my truth. … 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."

MacFarlane had no comment, however, on the troubles facing costar Rob Lowe.

Luke MacFarlane, who was spotted out last year with Prison Break Star Wentworth Miller, has confirmed that he is gay.

Referring to his on-screen story line - in which MacFarlane's character, Scotty Wandell, marries his partner, Kevin Walker - Luke added:

"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. It's telling of the beginning of more waves and I'm very proud of that."

We agree.
