Justin Bieber stills sleeps with the lights on.

The 18-year-old singer is still afraid of the dark so he "sometimes" feels the need to keep his room illuminated in case he gets scared during the night.

Justin's father Jeremy Bieber said: "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."

Despite being afraid of the dark, the 'Boyfriend' hitmaker knows God is looking after him and he feels "blessed" to be in such a privileged position within his life, so much so he thanks the Lord on a regular basis.

He explained: "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's blessed with the talent and the opportunity and everything. I feel like there's also a reason I'm here."

The 'Never Say Never' singer is also thankful for not having much facial hair at the moment, although he is expecting to have a bearded face in years to come.

He added to The Sunday Times magazine: "I shave, yeah. But not often. I only grow a little moustache. It's good to not have that much, right? Some guys have to shave every day. Twice a day! My dad has to shave often, his face gets a lot of hair. So I probably will."
