The 51-year-old star took to Instagram to share videos and photos from the milestone event, showcasing the joy and pride she felt for her son's achievement.

In the videos posted by Klum, she and her husband, Tom Kaulitz, could be heard cheering for Henry in the background as he walked out of the auditorium, donning a purple gown and cap with a white stole layered on top. Klum's caption overflowed with love and admiration for her son, exclaiming, "CONGRATULATIONS HENRY... We are all sooo proud of you ❤️. You did it, my beautiful boy. College here we come 🥳🎉 SHINE BRIGHT ❤️."

Following the graduation ceremony, Klum captured the evening's festivities on her Instagram Story. The celebrations included a private dinner, complete with "Congrats Grad" confetti decorating the wooden table and matching balloons. Klum also indulged in a delectable selection of desserts, proudly displaying her plate of treats.

In one selfie video posted by Klum, she and Henry playfully puckered their lips and made kissing noises at the camera, further demonstrating the joyous atmosphere of the celebratory occasion.

Later, Klum shared a photo from the dinner, which appeared to feature her, Kaulitz, Henry, and her three other children: Leni, Johan, and Lou. The family's celebration was extended to include some of Henry's friends, creating a joyous and supportive atmosphere.

Klum's eldest daughter, Leni, also recently graduated from high school in 2022 and made a significant move to New York City to start college. However, Leni has taken after her mother's footsteps and embarked on her own modeling career. The young model even had the opportunity to star alongside Klum in a lingerie campaign for the upcoming 2023 holiday season, further solidifying her journey into the fashion industry.

Heidi Klum's ecstatic celebration of her son's high school graduation reflects the love and pride she has for her family. The star-studded event marked an important milestone, signaling not only the completion of Henry's high school education but also the beginning of new chapters and exciting opportunities for him and his siblings.
