During an appearance on "The Tonight Show", the "Jurassic World" star said he has not been completely honest with his son Jack, two, about his career, reported People magazine.
Jack, whose mother is Pratt's wife actress Anna Faris, "loves everything trucks, cars and automobiles so much so, that he is convinced his dad is a truck-driving firefighter."
"I know this because I'll say 'Hey bud, I'm gonna be back tomorrow. I gotta go to work;," Pratt, 35, said, adding, "And he'll go, 'Um, are you going to work on your fire truck?' And I'm like 'Yes, I am, son'.
