Leonardo Dicaprio is not certain about marriage

London: Hollywood superstar Leonardo DiCaprio, who is dating model Bar Rafaeli, admits he is unsure whether he will ever get married.

The actor, whose close friend Kate Winslet split from director spouse Sam Mendes soon after the three of them had worked on `Revolutionary Road`, admits seeing other people`s failed marriages has put him off tying the knot, a news website reported. Dicaprio said, "I don`t know whether I`ll ever get married. I`ve seen too many supposedly happy marriages go down. I`ve been as shocked as anyone." "No one can look at the marriages of other people and make a judgement. I don`t know the private lives of the actors I work with. I just know if they are good actors or good directors," he said. The `Inception` star also admitted he is unsure whether he would be comfortable with his girlfriend being on set if he had to shoot a love scene. "It depends on the circumstances. It all sounds very strange to people who`ve never been on a film set. There`s a group of people on one side of the camera and it`s all about lighting, angles, sound and getting your lines right," he said. PTI
