Victor Garber’s gay, he confirms — but didn’t you know already?

Actor Victor Garber confirmed Monday that he’s gay -- though he did it in a didn’t-everyone-know-already way.

“I don’t really talk about it but everybody knows,” Garber told the Greg in Hollywood blog about living with his same-sex partner, Rainer Andreesen, for more than a decade. “He’s going to be out here with me for the SAG Awards.”

E! News confirmed the info, while People linked to an April 2012 interview in Canadian magazine FYI in which the “Alias” and “Titanic” actor had mentioned his relationship with Andreesen, noting it as one of his proudest achievements.

“My companion Rainer Andreesen and I have been together almost 13 years in Greenwich Village. We both love New York.”

Andreesen was reportedly Garber’s date to the Golden Globe Awards on Sunday, where “Argo,” in which the 63-year-old actor appeared, took home best picture and best director.

Garber can be seen in NBC’s series “Deception.”
