Robin Thicke Enjoys Family Camping Trip...Shirtless!

There's nothing like the great outdoors!

After canceling his Friday night concert at the Indiana State Fair because of a "scheduling change," Robin Thicke was spotted spending some quality time with his son, Julian, instead.

The father-son duo traveled to Lake Perris, Calif., where they enjoyed a classic camping trip by the water.

Thicke was spotted with sleeping bags, snacks and water toys for the fun adventure Friday afternoon. He even stepped out of a giant tent (shirtless, mind you) he specifically packed for the trip.
