"Mad Men" star Elisabeth Moss and longtime "SNL" castmember and "Portlandia" creator Fred Armisen were married in October 2009, but they separated just eight months later before officially divorcing in May of 2011.

Moss has mostly kept quiet about what went wrong between the two. Until now.

"One of the greatest things I heard someone say about [Fred] is, 'He's so great at doing impersonations," she tells Page Six Magazine. "But the greatest impersonation he does is that of a normal person.' To me, that sums it up."

Oh, you actors! Armisen has admitted in the past that he's, well, a bit "off."

"I still haven't been able to put things together as a responsible adult," Armisen told Page Six Magazine in December 2010. "I didn't have a girlfriend until my last year in high school."
