Heidi Klum (52) congratulated her son Johan on his 19th birthday with a loving message on Instagram. Alongside a selfie with her second-oldest son, she wrote on Saturday: “Happy 19th birthday, Johan. Watching you grow up has been the greatest joy of my life. I am so proud of the young man you have become. Your future is bright – just like you. I love you so much, my son.”

 

Klum also shared a series of videos and photos in her Instagram Story showing Johan as a younger child. The mother of four regularly provides glimpses into her family life and especially likes to use her children’s birthdays to share memories from their childhood – for many years she did not show the children’s faces publicly.

Brother Henry also sends congratulations

Johan’s brother Henry (20), who is one year older, also congratulated him on his birthday via Instagram: Alongside a beach photo from their childhood, he wrote: “Happy birthday, Johan! Love you, twin.”

 

Johan Samuel is the youngest son of Heidi Klum and her ex-husband Seal (62). After his high school graduation in summer 2025, he began studying in New York City in the fall. In addition to Johan and Henry, Klum has daughter Leni (21) and youngest daughter Lou (16).
