Leonardo Dicaprio acts ''like a complete idiot'' to relax.

While the 'Django Unchained' star takes his movies ''very seriously'', he likes to unwind after a busy day of filming by meeting up with his friends and just being himself by acting the fool and discussing ''absolutely nothing of importance''.

He said: ''I take what I do very seriously when I'm on the set that's all I focus on. So my vice is to hang out with my friends, talk about absolutely nothing of importance and act like a complete idiot.

''It's like therapy to just be a complete idiot with my friends.''

But Leonardo hasn't spent time in Los Angeles with his friends for ''a year and a half'' because of his busy filming schedule - which has seen him shoot 'Django Unchained', 'The Great Gatsby' and 'The Wolf of Wall Street' - and he is ''looking forward'' to some home comforts when he has finished his promotional work.

He explained: ''I love to have friends over, but I haven't really been home for a year and a half so I don't even remember the last time I did that.

''I've just done three movies back-to-back, so I'm looking forward to getting back to my house.''

When the 38-year-old star isn't at home he loves to escape from his busy showbiz lifestyle by diving underwater and ''disconnecting from earth''.

He added to the Daily Mirror newspaper: ''I love diving - it's one of my favourite things. I've been to a lot of different places around the world and sought out coral reefs and different species to see underwater.

''It's a whole new experience when you're down there. You really disconnect from earth and you're almost in a dream world.''
