It's Leonardo DiCaprio's birthday yesterday and he finally turned 40! There is a saying that goes "life begins at forty". This means that by the time you've reached this age, you have enough skill and experience to do what you want with your life. But the question is, "What does Leo want to do with his life?"

"The Wolf of Wall Street" star is known for his bachelor lifestyle. Even if he already has a girlfriend, he continues to party and flirt with other women like he is still single. Relationship expert Tracey Cox gave her suggestion on what Leo DiCaprio should do with his life now that he is 40 years old.

Cox told Now TV (via Entertainment Wise), "Leo has had a sparkling career that has seen him star alongside some of the world's most glamorous women, but hasn't had the same success with his off-screen love life."

She explained, "Forty is the time that many bachelors think about settling down, so we thought it would be interesting to see what components might make up his perfect match." We're sure that her mother would be the happiest woman on earth if Leonardo DiCaprio announces on his birthday that he is ready to get married.

We reported a few weeks ago that Irmelin DiCaprio has allegedly stepped in and tried to convince her son to change. A source revealed to OK! magazine, "She's been begging him [Leo] to put his partying and womanizing behind him." The insider added, "She's sick of getting attached to whomever he's dating, only to see then cast aside for a newer model."

Leo DiCaprio has dated some of the hottest supermodels in the fashion industry and he is currently dating Toni Garrn. Do you think the 22-year old German model will finally get him to walk the aisle or would she end up as part of his list of ex-model girlfriends?

In celebration of Leonardo DiCaprio's birthday, here's a slideshow of the gorgeous women in his life.
