Oh, baby! Is Jacob Roloff's fiancée pregnant? That's a hard "no," according to Isabel Rock. The Little People, Big World star took to Instagram stories to share a screenshot of comments that flooded her feed regarding baby No. 1, but she quickly shot down the rumors.

"I can see my summer bod is coming in nicely," the soon-to-be bride, before adding, "Not pregnant, just eatin' good." LOL. Yas, girl.

Over the weekend, the 22-year-old shared photos of their engagement party, but one member of the family was noticeably absent — Jacob's dad, Matt. Although his ex, Amy, was given a shoutout, there was no mention of the Roloff family patriarch at all. "One of my favorite parts about the day was how much these two, my dad and Jacob's mom got along ?," Izzy 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."

Jacob popped the question while the couple was 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 Jacob is pretty pumped about his future wife, too. He gushed on Instagram, "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." So cute! An exact wedding date hasn't been made public, but the duo did reveal they'll be getting hitched in 2019.
