In the first slide, she shared a sweet throwback picture of herself cuddling little Jack who can be seen wearing a grey shirt and dinosaur-printed trousers. She caption the photo, “Happy birthing to this sweet peanut!" The following slide featured a more recent photo of the duo posing while wrapping their hands around each other. Bundchen gushed over the teenager, writing "Who turned into this beautiful, kind, and incredible young man.

" "We are so lucky to have you in our lives! Love you so much!" she added. It is pertinent to mention that Bundchen's ex-husband Tom Brady shares his son Jack with his ex Bridget Moynahan.
