According to the Daily Mirror (which I warn you is one of the most disreputable british newspapers) says it's all true:
NEWS that Leonardo DiCaprio is planning to wed stunning girlfriend Bar Rafaeli in the summer shocked many. But now we may know the real reason they're getting hitched so quickly. Word reaches us that the couple, who have been dating for just 15 months, are expecting their first child.
Friends claim that Bar - who is the first Israeli model to appear in Sports Illustrated magazine - is due in late autumn. They add that she and Titanic hunk Leo are "delighted". An excited Leo has said he can't wait to be a dad, especially since his best mate, Spider-Man star Tobey Maguire, became a father last November.
Our spy reveals: "He dotes on Tobey's little girl Ruby and has been asking him all about what it's like being a dad."
There was speculation last month that 21-year-old Bar might be pregnant when she wore a loose-fitting top to a bash at Jet Nightclub at the Mirage Hotel and Casino in Las Vegas. She also stuck to mineral water all night. Leonardo, 32, is thought to have proposed very recently, and when he and Bar holidayed in Israel she is said to have officially introduced him to her family - and held a secret engagement party there.
American reports suggest they will have a private wedding ceremony in Israel, followed by a bigger bash in the US toward the end of the year. We can reveal that Leo's people have already been in contact with several exclusive venues in Tel Aviv about catering for various aspects of the wedding. The five-star Dan Accadia Herzliya Hotel has been contacted about staging the wedding party, while sources at the lavish King David Hotel in the Old City say Leo's people have asked about holding the ceremony there.
Personally, I doubt it very much. But hey, we promised you all the news so you're getting it!
