Titanic star Leonardo Dicaprio and model girlfriend BAR RAFAELI are reportedly expecting their first child together. Friends of the pair tell British newspaper The Daily Mirror that Rafaeli - the first Israeli model to appear in Sports Illustrated magazine - is due in late autumn (07). And DiCaprio is already getting in practice for being a father after doting on his best friend Tobey Maguire's baby. A source says, "He dotes on Tobey's little girl Ruby and has been asking him all about what it's like being a dad." The pregnancy news follows reports that DiCaprio has allegedly proposed to Rafaeli, and will have a private ceremony in Israeli, followed by a bigger party in America by the end of the year.
