Victor Garber has confirmed he has a long-term relationship with Rainer Andreesen.

The Argo actor has never publicly addressed his sexuality, but said he is planning to attend the screen Actors Guild (SAG) Awards later this month with long-term partner Rainer Andreesen.

Asked about an entry on his Wikipedia page – which is not official and open to editing by users – that says he lives in New York City with the artist-and-model, the 63-year-old actor told blog Greg in Hollywood: “I don’t really talk about it but everybody knows.

“He’s going to be out here with me for the SAG Awards.”

Six-time Emmy nominated Victor Garber first acknowledged Rainer Andreesen in an April 2012 interview with Canada’s Forever Young.

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

The former Alias actor can next be seen in NBC drama series Deception and says the drama series is like “dessert” because it is everything he ever wanted.

He said: “I’m a lucky actor, I work. But this is the first series that’s come along since Eli Stone, three years ago, that I really wanted to do.

“It was smart, it was interesting, it was dynamic and it wasn’t like the show was going to rest on me.

“I thought this was the perfect thing at this point in my life. It had everything I like, the complexity of the character, the family drama, all of the duplicity.

“For an actor, it’s like getting a dessert – like getting what you hope for and rarely get.

“I love to work and I love the idea of going to work every day and also the fact that I get to do it in New York. It’s like a gift. I feel like I won the lottery.”
