Hollywood hunk Leonardo Di Caprio is getting serious about his long-term girlfriend Gisele Bundchen. According to The Sun, the 30-year-old Titanic star, famed for his fondness for turbulent night life, expressed his readiness to settle down with the Brazilian supermodel.

“I’ve been with Gisele for four years now, and we’re happy together. Monogamy is the key to a good relationship.

“When I was younger I had a lot of fun. I’ve had my fair share of models,” said Leo, who has been awarded with a Golden Globe for his role in The Aviator.

On her part, Gisele has admitted that she would love to have a family with DiCaprio.  "I want three children,” she said last week. “But I want to be in a happy marriage."
