You could call them the most eligible bachelors in the world.

Five of the wealthiest men on earth are still unmarried, according to Wealth-X, a company that conducts research on the super-wealthy. With Valentine's Day in mind, they provided us with a list of the richest bachelor in their 20s, 30s, 40s, 50s, and 60s. These five tycoons are worth a combined $90 billion, and none of them are currently married.

From American tech moguls to the richest person in Saudi Arabia, here are the wealthiest bachelors around the world.

20s: Evan Spiegel

Net worth: $2.1 billion

Age: 25

Country: US

While still a student at Stanford in 2011, Evan Spiegel helped found Snapchat, the messaging app that lets users send disappearing photos to friends, with his classmates-slash-fraternity brothers Reggie Brown and Bobby Murphy. The app took off, making Spiegel a bona fide billionaire by age 23. Today, he continues to run the $16 billion company as CEO.

He hasn't tied the knot yet, but it's no secret that Spiegel's been dating supermodel Miranda Kerr. The pair are often photographed out in Los Angeles, and Kerr is all smiles talking about him. "He's just a really kind person and very genuine and very authentic and I really appreciate that about him," she told E!.

30s: Lukas T. Walton

Net worth: $10.6 billion

Age: 30

Country: US

An heir to the Walmart fortune, Lukas T. Walton is the grandson of the superstore's founder Sam Walton. The young Walton is worth nearly $11 billion, but the extent of his wealth only recently came to light, when news broke in November that he had inherited twice as much as his mother, Christy, after his father John died in a plane crash in 2005.

Walton's always stayed out of the public eye and continues to keep a low profile — little is known about the secretive heir, and he's rarely, if ever, photographed. As a child, Walton was diagnosed with cancer, but survived. He went on to earn a degree in environmentally sustainable business from Colorado College and is now a partner at Cuna del Mar, a private equity firm that invests in aquaculture.

40s: Sergey Brin

Net worth: $35.8 billion

Age: 42

Country: US

As a Stanford PhD student in 1998, Sergey Brin partnered with classmate Larry Page to create BackRub, an early search engine. The project eventually morphed into Google — now called Alphabet — one of the largest and farthest-reaching companies in the world, worth a whopping $475 billion. While Page handles the more administrative side of running Alphabet, Brin focuses on developing the company's next big innovation, exploring "moonshot" projects and ideas.

Brin's personal life has gone less smoothly, however. In 2013, he separated with wife Anne Wojcicki, founder of 23andMe, and shortly after that she learned Brin was having an affair with Amanda Rosenberg, a Google employee who worked on Google Glass. The two divorced in May 2015 after eight years of marriage. Brin and Rosenberg are no longer together, either.

50s: Georg Schaeffler

Net worth: $21.4 billion

Age: 51

Country: Germany

Georg Schaeffler served in the German military and held a short career in corporate law in the US before jumping aboard his father's company, Schaeffler Group, the nearly$11 billion in sales ball bearings and auto-parts maker that Schaeffler now co-owns with his mother.

Schaeffler has four sons with his ex-wife, Bernadette Muehelm, but the couple have been divorced since around 2007. Schaeffler also previously had an on-again-off-again relationship with Erika Nazem, the owner of a Dallas gym. He and Nazem were reportedly registered to marry in 2013, but the relationship reportedly ended.

60s: Alwaleed bin Talal bin Abdul Aziz al Saud

Net worth: $19.9 billion

Age: 60

Country: Saudi Arabia

Prince Alwaleed built his fortune with savvy investments in a range of companies across the US and the Middle East. He founded Kingdom Holding Co. in 1980 and has since invested in everything from real estate to entertainment to education, with stakes in companies like Twitter, The Four Seasons, Time Warner, and Motorola.

The prince has been divorced four times, most recently parting ways with Princess Ameerah Al-Taweel in 2013. The pair remain on good terms, however — a position he strives to maintain with all of his exes. "I had three unsuccessful marriages, yet I have a very good relationship with these wives," he told Vanity Fair prior to his split with Ameerah.

Now meet five of the wealthiest bachelorettes in the world.

These five unmarried women are worth a combined $46 billion.
