Chris Pratt reflects on 'beautiful' wife and son: 'My greatest treasure'

Chris Pratt may have a booming film career, but the "Jurassic World" star knows his biggest success isn't on the big screen.

It's back home with the family he adores.
Need proof? Just take a look at the sweet photo of his son that he shared on Instagram — and the even sweeter sentiment he added to it.

In the pic, little Jack — still wearing his pajamas — stands next to a rainbow sunbeam on the wall. He looks absolutely adorable with his messy blond hair and massive grin.
But when Pratt looks at the photo, he sees more than that. The actor can't help but notice the resemblance between his 3-year-old son and his wife, Anna Faris.
