Catherine Zeta-Jones andMichael Douglas‘ first child has flown the nest.

“Let the lectures really begin! I love you Dylan. Good luck in the next exciting and enlightening chapter of your life,” the actress wrote.

Zeta-Jones and Douglas last marked a milestone with their son back in May when theyshared pictures of the then-high school senior heading off to prom. The actress shared a smiling selfie of the three on her Instagram and gushed about her son again, sharing that she was “so proud” of him.

Dylan became an uncle for the first time late last year when his older brother Cameron, from Douglas’ first marriage to Diandra Luker, welcomed daughter Lua Izzy with girlfriend Viviane Thibes in December.

Cameron, 39, posted a picture of Dylan cradling Lua while the rest of the family posed for the sweet shot on Instagram shortly after Lua’s birth.

“What it’s all about,” Cameron captioned the post in January.
