Back in June, Klum attended Henry's high school graduation with her husband Tom Kaulitz, celebrating the milestone with some sweet clips on Instagram.

Henry, dressed in a graduation gown and cap, was seen in one video collecting his high school diploma onstage as loud cheers from Klum and others were heard in the assembly hall. After posing for a photo, Henry walked offstage and past Klum, smiling as she shouted, “Yes Henry — woohoo!”

“CONGRATULATIONS HENRY. We are all sooo proud of you ❤️,” Klum wrote in the caption. “You did it my beautiful boy. College here we come 🥳🎉SHINE BRIGHT ❤️.”
