Jennifer Aniston and Justin Theroux‘s wedding seems to be in the running for the biggest kept secret of the year, and close friend Kathryn Hahn is still impressed they pulled it off!

“What I’m most happy and proud of is that they were able to do it as privately as they had wished,” Hahn, 42, told reporters at the Showtime “Emmy Eve” Party on Saturday. “It’s really amazing. It makes me very happy for them.”

Aniston and Theroux surprised the world when they tied the knot in an intimate ceremony in the backyard of their Los Angeles home in August.

“Guests were told it was a birthday party for Justin,” a source previously told PEOPLE. “Jen and Justin wanted to surprise guests and guests were certainly surprised.”

The couple, who got engaged in August 2012, jetted off to Bora Bora for their honeymoon with a few of their closest friends, including designer pal Jennifer Meyer, who happened to design the duo’s wedding bands.

“When anybody asks me to design something for them that’s meaningful, it’s such a flattering thing and it means a lot to me,” Meyer told PEOPLE at the “Women to Watch” lunch at Tory Burch in Beverly Hills hosted by Glamour‘s editor in chief, Cindi Leive, on Friday.

Though Hahn, who starred alongside Aniston in She’s Funny That Way, was hush-hush when asked how Aniston was doing as a newlywed, she did offer some input.

“I’m assuming awesome,” the actress told PEOPLE. “How could she not be? It’s totally exciting!”

Adding, “I am going to leave it as private as they deserve and worked hard, so hard, to manifest.”
