Elisabeth Moss and Fred Armisen

It seems being married to a comedian isn't all laughs, at least according to Elisabeth Moss.

For the first time, the Mad Men actress hinted at what went wrong in her marriage to Saturday Night Live star Fred Armisen. "One of the greatest things I heard someone say about him is, 'He's so great doing impersonations. But the greatest impersonation he does is that of a normal person,'" she told Page Six Magazine. "To me, that sums it up."

Moss, 29, and Armisen, 45, became engaged in January 2009 and married that October. The couple separated in June 2010 and filed for divorce three months later, citing "irreconcilable differences."

Neither party has commented on the split until now. "I'm probably gonna get a slap on the wrist," she said. "But I've just been such a good girl. And sometimes you just want to be a bad girl for a minute."

It appears Moss has zero regrets about splitting from the funny man, and it doesn't sound like she'll be settling down again anytime soon. "It's fun to go out at night and not know what's going to happen," she told the magazine. "I'm addicted and obsessed with my freedom in that sense. I'm having fun!"
