Elisabeth Moss will soon have a little more in common with single girl Peggy Olson. The Mad Men actress filed for divorce Monday from SNL‘s Fred Armisen after 11 months of marriage. 

Moss and Armisen married in October 2009, a year after meeting on the set of SNL for Jon Hamm’s hosting gig. Moss, 28, cited irreconcilable differences in her filing and listed June 26 as the date of their separation. Armisen, 43, has since started dating his 23-year-old SNL co-star, Abby Elliott

The source of their split? “Her religion was as important to her as their marriage, if not more,” one source told Us Weekly of Moss’s faith in Scientology. “He could not get with it.” –AMY LEE
