Rap star Lil Wayne's diamond teeth have turned the hitmaker into an obsessive compulsive - he brushes them morning, noon and night.

Amazing, but not best

I hate rap

The flamboyant star has gems fixed to his teeth and cannot remove them, so he's careful what he eats and always takes care to brush them after every meal.

He says, "I brush them after dinner, after lunch - with Colgate."

Lil Wayne estimates he has $150,000 worth of diamonds in his mouth - and they're permanent. He adds, "I can go to the dentist and switch them out, but it's surgery."
