If you were to take a guess at who is the world's most marketable athlete, where would you start? Lebron James? Tim Tebow, Tom Brady, Tiger Woods? Well, you'd be entirely wrong.

The world's most marketable athlete is actually Cristiano Ronaldo, arguably the best soccer player of all time. First off, he is playing professional soccer which is the most popular sport internationally. Secondly, this guy constantly has millions of dollars coming his way whether it is when he scores a goal for his national team Portugal or is even modeling for Armani.

According to Kurt Baudenhausen of Forbes.com, Ronaldo has made almost $43 million in the past 12 months alone. Oh yeah how about that shirt deal with Adidas? That's only about $50 million dollars a year. Ronaldo is only 27 years old and is breaking every record there is.

Lionel Messi is his main competitor in his sport but many say Ronaldo will be better in the near future. It seems like just a few years ago when people talked about soccer; David Beckham was a name that finally came up but now all you hear about is Cristiano Ronaldo and Lionel Messi.

Another reason Ronaldo is so marketable is his personal life. Ronaldo is by definition a playboy. He's always popping in and out of night clubs, landing supermodel girlfriends and causing a stir among the more conservative. Recently he posted updates about his new girlfriends on Twitter and has even posted updates on Facebook about his next photoshoot with Armani.

One big worry people have with Ronaldo is whether or not he's let the fame get to his head. Many say he's cocky or conceited but we'll let you be the judge of that. Regardless of his cockiness, do the math, if he keeps building up his image and scoring goals; this may be the richest athlete to ever suit up in a professional uniform.
