Saturday Night Live alum Jenny Slate is splitting from her husband of nearly four years, Dean Fleischer-Camp, PEOPLE has learned.

The pair, who co-created the children’s book, Marcel the Shell: The Most Surprised I’ve Ever Been, were married in September 2012. Together, they won Best Animated Short at AFI Fest 2010 for their Marcel viral YouTube videos.

“When the video went viral, there were so many different things we could do with it,” Slate, 34, previously told PEOPLE about the success of the stop motion animated videos. “But what we wanted to do first was make the books. And to make beautiful things for children of all ages – whether you’re 7 or 77, there’s a kid in there somewhere.”

Slate’s voice can be heard in the upcoming film The Secret Life of Pets, where she took on the role of Gidget, a fluffy white gutsy Pomeranian puppy.
