“Mad Men” star Elisabeth Moss and “Saturday Night Live” castmember Fred Armisen are engaged. The actress confirmed the news to USAweekend.com.

“It happened a few days ago,” Moss told the Web site during an interview about her SAG nomination. “It’s private, so I don’t want to share the details of how it happened, but I will say it was perfect.”

During the interview, Moss had to correct herself about her new status with Armisen, saying, “… actually, now fianc$#233;.” The couple has managed to stay under the radar until last week, when they were spotted getting romantic together at Vanity Fair’s “Mad Men” party at L.A.’s Chateau Marmont, reports TVGuide.com.

TVGuide.com also reports that in a recent interview, Armisen talked about hanging out with his girlfriend “Lizzie” backstage at the production of “Speed-the-Plow,” the play Moss currently stars in. Moss also recently made an appearance on “SNL,” when her “Mad Men” co-star Jon Hamm hosted.

“I love that I get to be in New York. I moved to New York at 19 because I wanted to do theater,” Moss explained to USAweekend.com. “I ended up doing more TV and films and went back and forth between New York and L.A., so this is a kind of a lucky happenstance.”
