The family pic was one of several highlights for James, who also shared photos of himself hanging with friends and going to a Los Angeles Lakers game alongside the caption, "Cheers California."
Sarah and Matthew have largely kept their kids out of the spotlight, but the trio have made the occasional red carpet appearance. In fact, James attended the premiere for his dad's movie No Hard Feelings in June and even posed for photos with his parents.
And their family hobby translates into the main philosophy Sarah teaches her kids: to work for what they want. "Books and food and interesting experiences, and they're warm in the winter and cool in summer," she noted. "But they should pine for things, they should want things."
