Apparently, the sheen of the Cannes Film Festival can only last for so long. Five months ago, Leonardo DiCaprio and Blake Lively met at the annual event and began dating soon after. However, reps for both actors have told Us Weekly that the relationship is now over. The two were first spotted aboard Steven Spielberg's yacht on May 17. Throughout the summer, DiCaprio and Lively were seen in Italy, California, New York, and even Australia, where Leo was filming 'The Great Gatsby.' Although they are done, reps say DiCaprio and Lively remain friends.
