Mad Men's Elisabeth Moss engaged

Mad Men's Elisabeth Moss engaged to Saturday Night Live's Fred Armisen

It's been just a week since news hit that Elisabeth Moss is dating Saturday Night Live's Fred Armisen – and now it's been confirmed the pair are actually engaged.

Moss - who also starred in the West Wing and Grey's Anatomy - told usaweekend.com: 'It happened just a few days ago...It's private, so I don't want to share the details of how it happened, but I will say it was perfect.'

Armisen and Moss have been spotted on a string of dates recently, including a night at the Vanity Fair party for Mad Men, and also at her Broadway production, Speed-the-Plow.

Congratulations!
