Deacon, 13, and Tennessee, 4, were all smiles in Tennessee's pre-school classroom. And, even sweeter than the boys' smiles is the story behind this pic.

Tennessee's last day of school coincided with "share day," and the four-year-old decided to share one of his favorite things: his very own teenage bro. (Who, it so happens, is a dead ringer for Leonardo DiCaprio.) Is that not the cutest?

From sipping milkshakes to hikes and pizza night, we know this family has a blast together—and we're sure their summer will be epict.

My guys staying cool #nashville #summertime ????
