The stars of TLC's "Little People, Big World," Matt and Amy Roloff, announced on Friday that they are filing for divorce after 27 years of marriage, reports Us Weekly. They had separated in March 2014, although they continued to co-parent and run their family farm in Helvetia, Oregon.

The reality show "Little People, Real World" has been on TLC since 2006 and chronicled the Roloff family as they lived their everyday lives. The five Roloffs  include twins Jeremy and Zack; Molly; and Jacob. Jeremy is the only Roloff family member who does not have dwarfism. 

"After 27 years of marriage, it is with great sadness that we have come to the difficult decision to file for divorce," the couple told Us Weekly. "We are proud of what we have accomplished together, including raising four wonderful children who have grown to become remarkable adults and building our strong and ongoing successful business."  

Last year was hard for the couple,  Matt said on the TLC show in a promotional clip last year, and as a result he moved to the guest house.

"Amy and I stuck it out for years when maybe we shouldn't have," he said. "I never quite felt at home in my own home, so something needed to change." Added Amy, "It's not my choice for him to leave. I am saddened by it. It's been 26 years. We don't have a plan for how we're going to work this out, so it's not going to be easy."

The couple plan to continue working on the ventures they have together, according to their joint statement to Us Weekly.

"We would like to thank our family, friends and all our fans for their continued support and understanding during this difficult time."
