According to some media reports, Leonardo Dicaprio has been dumped by his model girlfriend. Bar Rafaeli reportedly ended the couple's six-month relationship because she found it hard to deal with the actor's work schedule and partying. "Bar is a professional model so she has to be healthy and look great every day, so there is no way that she could keep up with that kind of decadent lifestyle," a friend of the model told a British paper. "When they were apart she worried about what he was up to and in the end decided it would be easier and less painful just to say enough is enough."
