The model marked the milestone moment with videos and photos on her Instagram on June 7.

Heidi Klum is one proud mom!

On Friday, June 7, the former Project Runway host, 51, shared sweet clips on Instagram of her 18-year-old son Henry’s high school graduation as she attended with her husband Tom Kaulitz.

“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 ❤️.”

Henry, dressed in a graduation gown and cap, was seen in the first 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!”

In another clip, Henry walked out of the hall with his fellow students, past Klum again as she shouted at him, “Yay Henry!” He, in response, said, “Thank you!”

A smiling Klum appeared in a final clip from during the graduation ceremony as she sat with Kaulitz, 34, in the audience, who had his arm around her.

On her Instagram Stories, the model also posted a video of her beaming in the car on the way to her son’s graduation with an animated caption that read, “Happy Graduation,” with an illustrated graduation cap with sparkles added. She also posted a video of her in the audience at the graduation with Kaulitz.

Klum later posted a photo from Henry’s celebratory dinner afterward as she was joined by her husband and Henry, and what appeared to be her children Johan, 17, and Lou, 14, shared with her ex-husband Seal, and daughter Leni, 20, along with friends as they sat around a table.

“Celebrating HENRY ❤️🥰🎉,” she wrote in the caption.

Klum shared more footage of the get-together on her Instagram Stories as she posted a clip of an array of balloons for Henry that read, “Congratulations Grad” and a shot of her plate of desserts. She was joined by Henry in another sweet clip as the pair embraced outdoors.

Klum’s son Henry’s graduation comes a week after celebrating her 51st birthday on June 1.

To mark the occasion, the model posted photos of her joined by her family for a birthday meal on Instagram, along with a photo of herself as a newborn with her mother, Erna Klum.

“51 years ago ❤️,” she wrote in one caption, adding, “All I could wish for.”
