"Henry you’ve taught me so much, everything from you’re undying compassion, to your humility and kindness toward others. I am so proud and privileged to be your father," he continued. "HAPPY BIRTHDAY 🎂 🥳 I love you, -Dad."

Last month, the model mom enjoyed attending Beyoncé's Renaissance tour with Henry and Lou, with Henry well over a head taller than the 5'9" runway star as they walked together.

"@beyonce 🥳❤️🎉💃🏼 Happy Birthday 🥳🥳🥳🥳🥳🥳 #renaissance," she wrote in the caption.

During a February 2023 appearance on the Jennifer Hudson Show, Klum talked about the possibility of having more kids.

"I mean it's a lot. I've done it four times," the model said. "And I breastfed eight months each time and then I was pregnant again. Three times in a row. Again [my children are] 18, 17, 16 and then 13, so I was like…" she said, snapping her fingers multiple times.

However, she eventually said that she'd "waited a long time," and revealed that she "maybe" would be open to having more children.
