Matt Roloff of "Little People, Big World" just had his 56th birthday and it sounds like he snubbed one person for the big celebration. Amy and Matt have split, but they are still very involved in each other's life due to having kids together and working together on the Roloff farm.

What did Matt do for his birthday?

On Saturday, Matt Roloff had a big surprise celebration for his birthday at the farm. They are really busy right now with pumpkin season. The TLC cameras were not rolling, but it sounds like it was a fun time for all. The rest of the Roloffs were at the event along with Matt's new girlfriend farm manager Caryn Chandler.

She already worked for the farm before they ever started dating each other. It does sound like Molly didn't come down for the big event.

They had a cake and birthday party hats and it sounds like it was a big surprise for Matt who didn't know they were going to be having a party for him. A source explained saying, "'Caryn even made sure some of the farm hands were there as well, and gave out party hats to some of the crowd who had gathered behind the main gift shop."

What was Amy doing during the party?

It turns out that Amy Roloff wasn't invited and was actually left behind working at the Roloff farm during the party. She was doing meet and greets with the public and wasn't invited to the party at all from what it looks like, which of course, couldn't have made her very happy.

This was also allegedly Baby Jackson's first day to be at the farm during pumpkin season and Amy was left out of that as well. The source said that Amy and Caryn didn't speak to each other at all during the day either.

Right now, the Roloff farm is open to the public. If you have ever wanted to meet them, this is a great way to do it.

Amy and Matt Roloff got a divorce back in 2016. Amy still lives in the big house on the Roloff farm, but Matt and Amy both still work there together. Amy and Matt have both moved on. She is dating Portland realtor Chris Marek, but it sounds like he wasn't there for the Big Birthday event either. Maybe Amy didn't even want to go, but it did look odd to people who were there that she seemed to be totally left out of the fun.

Are you surprised that Matt Roloff left his ex-wife Amy Roloff out of his birthday celebration? Do you feel like these two will ever quit working together to make life easier? Sound off in the comments below, and don't miss new episodes of "Little People, Big World" when they return to TLC.
