"Happy Birthday Billy Boy. You are everything beautiful and meaningful in my life. Seeing you so full of wonder, so content, lights a warmth in me that gets rid of all the shadows and doubts of life," Stamos wrote in his caption.

"You, in your innocence and joy, make every challenge worthwhile. God only knows where I’d be without you, my dear son. You and your sweet mother are my purpose, my joy, my everything."

In December, the Full House alum was photographed on the red carpet at the Wonka premiere in Los Angeles, walking with son Billy and wife Caitlin McHugh Stamos, 37.

Wearing a pastel blue suit and sunglasses, Stamos hugged his son as they posed for a father-son photo together with a Wonka chocolate bar as the backdrop. Billy opted for a red velvet suit and sat on his dad's leg, smiling for the cameras.

Stamos and his wife also posed for a cute family photo with Billy, placing their son in between the two of them.

Later, the star posted about the event on his Instagram, sharing a few photos and a video of his family of three.

"We got the golden ticket to the premiere of @wonkamovie last night! It was such a treat to bring Billy with us to this one. He was so excited and we all loved the movie. Thanks for having us! Go see #WonkaMovie this weekend 🍫," he wrote in his caption.
