The Black Eyed Peas singer Fergie claims to survive on just one hour's sleep each night. The star, real name Stacy Ferguson, compares herself to former British Prime Minister Margaret Thatcher, who famously only slept for a few hours each night.

Fergie says, "You can't assume any success. Usually artists spend time in the studio recording an album, then they do prep, then they do press. And then they tour. Most find it hard but I love it. I have about an hour's sleep. I'm like Margaret Thatcher."
