The gold truck that Katy Perry hired to promote her upcoming album, 'Prism,' was hit by a drunk semi-truck driver.

The accident occurred in a Pennsylvania Walmart parking lot, and the truck's driver was inside the super chain store when the incident happened. Everyone else involved is otherwise OK, and Perry was nowhere to be found.

According to TMZ, the other driver hit the front cabin of the truck and fled the scene before the inevitable guilt had them returning to the site of their crime -- or possibly because someone might have noticed someone else driving into an enormous gold truck.

The accident caused "substantial damage" to the vehicle, and the driver was arrested for driving under the influence.

Now we're just left with one question. What's inside the truck?
