Chris Pratt, 43, recently posted a shirtless photo while on the set of Prime Video’s The Terminal List — but it wasn’t his abs and fake wound that his followers noticed. Instead, Pratt’s 9-year-old son Jack stole the moment.

“Lookin cut,” Pratt captioned the photo, which was taken in his trailer. A closer look reveals a cute sticky note left by Jack that read: “See ya at 8:00 ish,” signed with a heart and his name.
