Justin Bieber sleeps with lights on

The 18-year-old 'Boyfriend' singer's father Jeremy said that Justin keeps his room illuminated in case he gets scared during the night, reported Contactmusic.

"My hands sweat a lot, so do his. And his feet. They don't smell. And he was afraid of the dark for most of his life," Jeremy said.

Justin said that he thanks the Lord on a regular basis.

"God means a lot to me. I pray when I go to sleep. I pray during the day, when I have a problem or when I just want to thank him for all he's done for me. Without God I wouldn't be in this position," he said.
