Gwyneth Paltrow is celebrating her son on his big day!

On Monday, April 8, the Goop founder, 51, shared a photo on Instagram of her son Moses in celebration of his 18th birthday.

In the snap, the newly minted adult looked serious as he wore a navy blue shirt and peered directly into the camera. "Happy 18th birthday to you, my son. I am so proud of who you are. I love your sensitivity and brilliance and quiet humor," the proud mom wrote in her caption.

"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."

"There is such a magnificent world of ideas and harmonies inside that beautiful head of yours. 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. ❤️Mama," she concluded the sweet dedication.

Paltrow shares her daughter Apple, 19, and son Moses with husband Chris Martin.

In March, the actress spoke with The Sunday Times and shared her feelings about how her son Moses is leaving for college in the fall.

"In the fall, Brad [Falchuk] and I have boys that will be going off to university," Paltrow said of her son Moses and her husband's son Brody. "It'll be interesting to see how the morning routine changes with no kids in the house."

"On the one hand, incredible sadness. A deep sense of impending grief," the actress said of how she feels about the kids leaving. "On the other hand, this is exactly what should be happening."

"Your kids are supposed to be, you know, young adults who can achieve and cope and make connections and be resilient. That's exactly what you want. And that means they leave the house."

Paltrow added that she's "been so defined and so fulfilled by motherhood."

"It's like the guiding force. It's what I return to. I observe a lot of my friends who've had kids who've gone off to college. Your kid...it changes. And you know, they come home a lot and all that stuff, but it's not quite the same as living under the same roof all the days of the year. So I'm just trying to be open to what that means."
