DICAPRIO: 'TITANIC NEARLY RUINED ME'

The 34-year-old became a heart-throb all over the world at the age of 23 after landing the lead role in the 1997 film alongside Kate Winslet.

But DiCaprio admits he was not mature enough to cope with turning into a major Hollywood star overnight - and the years following the movie's release saw him become a completely different person.

He says, "Titanic began a period of rebellion for me. As soon as people give you enough compliments and you suddenly have more power than you've ever had in your entire life, it's not that you become an arrogant p***k, or you become rude to people, but you get a false sense of your own importance. You're treading in dangerous territory when you begin thinking you've altered the course of history. It was like a runaway train. I didn't understand what was happening to me."
