THE Black Eyed Peas leader WILL.I.AM has two must-have items that help him sleep on tour - a lucky T-shirt and his favourite pillow.
The My Humps hitmaker reveals he can't relax after shows unless he's wearing an unwashed night shirt and lying on the perfect pillow.
He tells Blender magazine, "The fabric really affects my s**t... I have nice dreams."
And the songwriter/producer insists on completing tours before washing his nightwear: "I don't like to wash my sleep clothes."
