Heidi Klum has marked her son Henry's 20th birthday by sharing a series of personal photographs and tributes on Instagram to her boy

She captioned her carousel of snaps: "We love you all so very much (red heart emoji) HENRY (red heart emoji.)"

The photos included images of Heidi cuddling Henry as a child, a picture of him smiling as a baby, and more recent shots of him playing a video game and looking into the camera.

Henry is one of four children Heidi shares with her former husband Seal, 62.

Their other children are Johan, Lou and Leni.

In August, Heidi shared a selfie with Henry, Johan and Leni as she moved one of her children into a college dorm in New York City.

She captioned the post: "College move in day NYC (red heart and Statue of Libreryty emojis.)"

That same month, Heidi attended the return of Kith's runway show in New York, where Henry made his debut on the catwalk.

Posting photos and videos from the event, Heidi said: "So many beautiful Models on the @kith catwalk in New York tonight, but I only have eyes for you @henrygunthersamuel."

The show took place on the streets of NoHo outside Kith's renovated flagship store and was the label's first runway event in six years.

Henry appeared in a denim-on-denim look, including a light wash jacket and jeans layered over a white bomber jacket and collared shirt, styled with white trainers.

The appearance came shortly after Henry signed a modelling contract with Next Management.

In a statement released by the agency in July, he said: "I've grown up around fashion and entertainment, but stepping into this world myself is a whole new experience.

"I'm grateful to Next Management for this opportunity and excited to learn, grow, and find my own voice in the industry."
