Hmm… Jacob Roloff’s Dad Matt Is Noticeably Absent From His Engagement Party

The Little People, Big World crew is expanding, but one member of Roloff family was noticeably absent from the festivities. Over the weekend, Jacob and his soon-to-be wife, Isabel Rock, took to Instagram to share photos from their engagement party, but Jacob's dad, Matt Roloff, didn't appear to be in attendance. Instead, Amy Roloff was given a shoutout from the soon-to-be bride.

"One of my favorite parts about the day was how much these two, my dad and Jacob's mom got along ?," she wrote. "Even though Jacob and I have been together for three years, they met for the first time this year. More photos because there were just so many and it was such a beautiful day."

The 21-year-old popped the question to Izzy while they were vacationing in Iceland and announced the news one month later. "We are finally ready to share with everyone… WE ARE ENGAGED!!! ??," she wrote on Instagram on Jan. 27.

And it seems like Jacob is pretty happy, too. He took to his own Instagram account just a couple days ago to gush about his leading lady. "We had our engagement party. So good to have Izzy's side of the family and friends see the farm and meet all my people. To be honest, though, I was very much preoccupied trying to figure out how I got so lucky ??? She was seriously breathtaking in that skirt … I've loved this lady for four years but boy does she still impress me… in more ways than one." Ugh, so sweet!

But just because Matt appeared to be MIA, don't assume they're feuding. The Out to See author recently squashed rumors he and his famous fam were beefing when he took to social media to write, "You know that feeling of dread when someone is scrutinizing you and you think, 'Hey, this might be true about me,' until they slip up and say something totally bonkers and wrong, and you sigh with relief because they are so off base? I feel this every. single. time. I see a headline regarding 'rifts' in my family. It is just so simply and surely untrue! This is a good picture of a pure, early, easy, fun time in my life."

He continued by adding an excerpt from his new book, which is set to be released on May 1. "My parents have always been pretty amazing. They both succeeded in life, had a family, and provided for and gave their kids all that they wanted, within disciplined reason. My dad taught me practical, mindful things like chess, how to build a fire, and other sorts of exercises in basic critical thinking to a degree that I still carry the lessons with me today. He was also a great storyteller, sitting all of us kids by the fire and telling stories of 'dark, windy nights.' My mom, always making sure we knew we were loved, supported all our efforts and hobbies as often as she knew about them, even coaching all of us kids in soccer in our early years. She also instilled in us a very good sense of manners and respect that I find myself appreciating more and more every day." Welp, there you have it!
