Schaech and Kramer, who met filming Prom Night in 2008, married in an outdoor ceremony on America's Independence Day (04Jul10) in Glen Arbor, Michigan in front of 100 of their friends and family.
But just a month into married life the stars have decided to end their union.
A spokesperson for Kramer tells EOnline.com, "Jana and Johnathon have agreed to dissolve their marriage.
"Jana is humbled by the outpouring of support from her fans, friends and family, and appreciates the respect of her privacy."
Schaech was previously married to Christina Applegate for six years before they divorced in 2007.
