[inline:100]Many entrepreneurial and driven bros aspire to be members of the billionaires club. However, we all know that "pimpin' ain't easy." Billionaire bachelors and captains of industry can't just date or marry an everyday simpleton when there's the risk of losing ten figures of wealth and power to a money-hungry gold digger. There's simply too much on the line when your annual income is higher than the gross domestic product of some third-world nations. Perhaps this is why there are so few billionaire bachelors in the world. According to the personal wealth arbiters at Forbes magazine, there were only 72 single and ready-to-mingle bachelors and bachelorette with billionaire status in 2009. Here at BroBible, we're mesmerized by sexy trophy wives and head-turning girlfriends. So we decided to round up the 15 hottest WAGS of billionaires and rank them according to their hotness. Most are hitched to their high-rolling hubbies until death -- or divorce -- do them part. In order to earn a spot on our list, each wife or girlfriend had to be connected with a bona fide playboy with a coveted position on Forbes' prestigious world billionaire list (sorry Tiger, Ronaldo, and Harvey Weinstein). We've included photo evidence for justifying our ranking, which is spread out across two different pages, so bank your comments until the very end.
