The 38-year-old "Great Gatsby" star, who has earlier dated top models including Gisele Bundchen, Bar Refaeli and Erin Heatherton, says shooting for movies around the world made it difficult for him to handle a relationship.
"Six months of being on location or being off in Morocco or someplace like that is not the best thing for a relationship", DiCaprio said.
The actor who is currently enjoying a career break feels he is in one of the most comfortable phases of his life, reported Contactmusic.
"Most recently, in the last few years, I feel way more comfortable than I've ever felt," he added.
