DiCaprio: 'Fame can drive you nuts'

Leonardo DiCaprio has revealed that he understands why some actors go "nuts".

The Shutter Island star, who was recently rumoured to be engaged to Bar Refaeli, said that it is very important to keep grounded when you're famous.

DiCaprio told Parade magazine: "Just because you've done a good performance once, doesn't mean you're always going to be good. That's why some of the greatest actors in the world have gone a little bit nuts.

"They're saying to themselves, 'What happened? You used to love me?' It's an easy trap to fall into. You just have to realise that when you're hot, you're hot, and when you're not, you're not.

"I know this is going to sound lame, but one of my favourite things is hanging out with my friends. They take me away from the world of showbusiness and keep me grounded. It brings me back to who I am."

The actor recently said that during production on Shutter Island he had suffered from "bloodcurdling nightmares of murder" and had found the experience "traumatic".
