Bruno Mars and Terrence Howard have something in common.

The 'When I Was Your Man' singer may be one of the most in-demand artists on the planet, but his own demands are a lot simpler.

Though he seemed impressed by other stars' concert riders (especially Marilyn Manson's infamous "hairless, toothless hooker," to which Mars grinned, "How cool is that?!"), he revealed that he's fairly low-maintenance.

"Mine is pretty boring compared to that stuff," he said sheepishly. So what does he actually ask for?

"Wet wipes!" he quipped. "Wet wipes and a bottle of wine and I am good to go."

The best part? Mars revealed that the wet wipes are for his own use (unlike Howard, who had more sexist purposes for his). Who knew that Grammy winners still needed rest stop showers?
