Will.i.Am likes to go out partying not to enjoy himself, but "to figure out exactly who I'm making music for".

The Black Eyed Peas star may be due to go on hiatus, but he revealed that he doesn't sleep a lot and loves to stay focused on his work, "I go out partying to figure out exactly who I'm making music for. You can't just guess."

"Is it true I hardly sleep? Well, I could sleep five times throughout the day in hour increments and get five hours."

"But I'm healthy, I eat right, feel right. If I'm DJing until three, I party until five, sleep around six, wake up at nine. And that's when I start thinking. Real thinking."

He is currently working with Secretary Hillary Clinton to launch a school exchange program, 'One Hundred Thousand Strong', that will send American children to China and you can watch him rapping at a recent BEP concert here:
