Chris Pratt is celebrating his first son Jack Pratt.

The actor’s mini-me turned 10 earlier in the week.

Pratt celebrated his son’s milestone with a touching tribute.

He uploaded a picture of a papa sheep watching over a baby lamb.

The “Jurassic World” star gushed over how fast his son has grown.

He described the little one as “smart, handsome, and kind-hearted.”

Pratt concluded, describing Jack as “the best son and buddy” he could ever ask for.

Pratt welcomed Jack with his ex-wife Anna Faris.

The former lovers were married for 8 years before ending things in 2018.
