Amy Roloff Celebrates Dad's 90th Birthday After Not Attending Matt's Dad's 80th Bash

Amy Roloff made sure her father got a huge 90th birthday celebration just weeks after she didn't attend ex-husband Matt's recent party for his dad's 80th birthday!

The summer has been a time of dueling parties for the divorced Little People, Big World stars.

Amy, 53, told fans that all of their kids and their significant others attended the bash for her father, their maternal grandpa Gordon Knight, who made the age 90 milestone.

While Matt's girlfriend, Caryn Chandler, had held court at the birthday party for his dad, Ron Roloff, in California, Amy's beau Chris Marek was right by her side for Gordon's celebration in Michigan.

On Tuesday, Amy posted an Instagram photo of herself sitting between her parents Gordon and Patricia at their home in Michigan as she continued her hometown visit.

The LPBW star lovingly wrote, "My parents! Hanging out with them at their cabin up in the U.P. of Michigan. What a wonderful time creating more special memories.

As RadarOnline.com previously reported, Amy was missing from Matt's dad's recent 80th birthday party in California, where all four of their kids made an appearance and Chandler looked like the perfect hostess.

Matt, 56, shared with followers a photo of the big family reunion/birthday party in a Sunday, July 22 Instagram post.

But Amy wasn't there – and fans soon learned she was going to vacation in her Michigan hometown this summer.

Amy has been taking a trip down memory lane as she's been visiting friends and family where she grew up during a break from the farm.

On Sunday, August 5, Amy posted a romantic photo of herself with boyfriend Marek in Michigan; he has been getting to know her parents during the trip!

Amy and Matt have made it very clear with their dads' birthday parties that although they are still reality show co-stars, they live very separate lives!
