"Happy 18th birthday to our gorgeous, smart, talented, and caring son," the 47-year-old actor wrote on Instagram Oct. 23, alongside a few photos from the celebration. "You are a true light in this world and are so loved by all who know you. We are lucky to be your mom and dad. Love you, pup.."
Ryan added, in parentheses, "I'd say we did pretty good @reesewitherspoon."
Reese, 46, shared another pic of herself with Ryan and Deacon at the event on her Instagram Story, writing, "We love you Deacon! You make us so proud!"
