Sir Paul McCartney has shunned expensive hotels in favor of camping.

The 66-year-old musician is currently on a U.S. road trip with girlfriend Nancy Shevell, and the pair decided to spend a night under the stars when they arrived at Bennett Springs State Park in Missouri last weekend.

A fellow camper said: "It was incredible to see one of the world's richest musicians going back to basics."

"They didn't seem to have a care in the world as they laughed and joked with each other."
