The Mad Men actress, 28, and SNL star, 43, reportedly split in May, almost seven months after getting married – but the comedian doesn't appear to be shying away from jumping back into the dating game.
Armisen, who was also previously married to English singer Sally Timms, has moved on with fellow SNL cast member Abby Elliot, according to reports.
"They are together," a source tells E! Online. "It is very new."
Armisen and Elliot, 23, the daughter of comedian and SNL alum Chris Elliot, were recently spotted on a late night dinner date getting cozy at a restaurant in Los Angeles.
Reps for Armisen and Moss had no comment.
