The couple married last October, but seem to have gone their separate ways in May.
Armisen, 43, is apparently back on the dating scene already, as he's been spotted getting cozy with fellow-"SNL" cast member Abby Elliott, 23.
The new pair were spotted in Los Angeles recently.
This was Armisen's second marriage. He and singer-songwriter Sally Timms divorced in 2004.
Abby Elliot is the daughter of comedian Chris Elliott, the former star of "Get A Life!" and himself a former "SNL" cast member.
