DiCaprio to be a father

'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.

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.
