'Can't Believe How Fast They Grow': Jon Gosselin Still Processing His Children's Graduation

It has been weeks since Jon Gosselin's children graduated from high school, but he is still processing the sequence of events. Soon, his kids will be off to college, leaving him an empty-nester.

Of his eight children, Hannah and Collin Gosselin live under Jon Gosselin's roof. He has watched them grow into amazing adults, ready to navigate the world independently.

The doting dad recently shared a throwback photo from Hannah and Collin's graduation that happened not too long ago.

"Still can't believe how fast they grow," he said alongside a picture with his kids in their togas. Jon also highlighted how incredibly proud he was of his kids.

Hannah and Collin also celebrated their milestone in June with Instagram posts. Hannah shared a photo of herself in a dainty white dress while holding a red bedazzled graduation cap.

Meanwhile, Collin shared several snippets from the event alongside a lengthy caption thanking his sister, Jon, and Jon's ex-girlfriend, Colleen Conrad, for being fantastic support systems for many years. Collin wrote:

"I would like to thank my dad, who has taught me so much about running into hard times and moving past them, about resilience."

Collin also revealed he would be visiting Parris Island soon after graduation and that he will be studying Mechanical and Industrial Engineering in college.

Although Jon, Hannah, and Collin no longer appear on television, they still have fans who watch their lives unfold through social media. One of them commended Jon Gosselin, who won custody of his two kids, for raising wonderful children despite the challenges. "You're a good dad," the fan said.

Besides Jon, Hannah has been active on social media in recent weeks, posting pictures with her Texas-inspired ensemble and other outfits. Her brother, Collin Gosselin, also has an Instagram account but rarely posts photos.
