The 32-year-old actor and his Israeli model girlfriend Bar Rafaeli, 21, are reportedly expecting their first child together this autumn.
Friends of the couple - who have been dating for 15-months - claim the pair are absolutely "delighted" with the news.
Leo reportedly felt the fatherhood urge after his friend, 'Spider-Man' star Tobey Maguire celebrated the birth of his first child last November.
A source told Britain's Daily Mirror newspaper: "He dotes on Tobey's little girl Ruby and has been asking him all about what it's like to being a dad."
The couple's happy news comes shortly after reports Leo proposed to Bar, followed by a secret engagement party in Tel Aviv.
It is believed Leo and Bar will marry in a private ceremony in Israel followed by a larger celebration in the US later in the year.
Leo has already contacted a number of exclusive venues in Israel, including the five-star Dan Accadia Herzliya Hotel and the plush King David Hotel.
'The Departed' actor started romancing Bar shortly after he split from supermodel Gisele Bundchen.
