The Roloff family is welcoming a new daughter-in-law! Last Christmas, former Little People, Big World star Jacob Roloff got engaged to his longtime girlfriend Isabel Rock, and Jacob’s mom Amy Roloff threw an engagement party to celebrate the couple’s upcoming wedding. The reality stars took to Instagram to share photos from the event, and Izzy shared a sweet messaage to reveal her favorite part from the day.

“One of my favorite parts about the day was how much these two, my dad and Jacob’s mom got along. 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,” she wrote in the caption on Instagram.

Meanwhile, her fiancé Jacob also revealed his favorite part from their day and he admitted that even though they were surrounded by family and friends, he couldn’t keep his eyes off of his bride-to-be. “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,” he wrote on Instagram. “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.”

And Izzy’s future mother-in-law, Amy, also couldn’t help but gush over their upcoming wedding. “What an awesome day celebrating Jacob and Isabel’s engagement [with] a party! Beautiful to bring two families and friends together,” the proud mom wrote in her Instagram caption. “They’re getting married next year. Thanks for everyone’s encouragement and support. I’m blessed [with] really great kids.” Watch the video below to get all the details about how Jacob proposed to Isabel!

Izzy got to spend time with all of her future in-laws, including Jacob’s brother Zach Roloff, his wife Tori, and their son Jackson, plus Jacob’s brother Jeremy Roloff, his wife Audrey, and their daughter Ember. But since Jacob’s parents Amy and Matt Roloff are divorced, they both already have moved on with other people, it’s unclear if Amy’s boyfriend Chris Marek or Matt’s girlfriend Caryn Chandler were invited to the family affair.
