The star added, “I’d say we did pretty good @reesewitherspoon.”

Deacon responded to his dad’s post, commenting, “Thanks dad!! I love you.”

Witherspoon also celebrated her son on Instagram, writing, “How did this happen?!! @deaconphillippe is 18?!! One day he was trading Pokémon cards, singing Bruno Mars songs, and playing American Ninja Warrior in the backyard. The next day, he is taller than me, cooking the family steaks on the grill and making his own music with his best friends. My heart is bursting with pride about the young man he is becoming. Happy 18th Birthday Deacon! I love you to the moon around the sun and all the stars ✨ 🥺❤️🎂”
