The 'Gladiator' star, who raises two sons together eight-year-old Charles and six-year-old Tennyson with Spencer, who split after nine years of marriage this weekend, reported the Huffington Post.
The couple's property interests alone are worth USD 50 million, including a USD 14 million penthouse in Sydney and farmland in New South Wales.
The paper estimates that Crowe, 48, has made some USD 150 million in acting fees since he and Spencer first met 22-years ago, and he also has a number of other business interests in Sydney, including a share in Rabbitohs football club, a gym and a company which supplies restaurants with beef.
Crowe and Spencer married in 2003, after first meeting on the set of "The Crossing" 13 years ago.
