Leonardo DiCaprio has been in the biz since he was a teenager so he's learned how to deal with fame, but he understands why actors "go nuts" after just a few years in Hollywood.
Leo, who shot to international fame after Titanic says it’s important to keep grounded when experiencing fame and success because it can be taken away very quickly.
He tells 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 realize that when you're hot, you're hot, and when you're not, you're not."
Leo, who is infamous for being a very private person, credits his friends for helping him stay grounded. They never let him act like a star.
He added, "I know this is going to sound lame, but one of my favorite things is hanging out with my friends. They take me away from the world of show business and keep me grounded. It brings me back to who I am. When I didn't want to go out in public after all the craziness surrounding ‘Titanic’, they sort of pushed me out the door. They were like, 'Are you going to hide out like a little hermit?' "
Oh Leo, we love you so much you can never do any wrong in our eyes!
