“I love your sensitivity and brilliance and quiet humor," the proud mom wrote in her caption.

She went on to say, "I admire how deep you go into areas that interest you, becoming an expert in synths from the 80’s and the French new wave. I love how much you love the people you love, but also how internal you are."

I am unbelievably proud of the person you are today, as you cross over the threshold into adulthood. I love you more than words can say, @mosesmartin you absolutely kill me. (heart emoji)Mama," she concluded the heartwarming caption.

As soon as Gwyneth shared the post her followers started comparing him with his father, on wrote, “He totally looks like his Dad : ).”
