If you're after a royal, you're in luck: the prince of this tiny
country is not reported to be dating anyone. This 23-year-
old heir to the throne of Liechtenstein also happens to be a
descendant of Charles I of England, spurring debates as to
whether he's a distant heir to the British throne too. He's
expected to inherit the lion's share of his family's $5 billion
(£3.8bn) fortune, so we can only imagine that wannabe
Robert Pera, 41, net worth: $7.8 billion (£6bn)
The billionaire founder of wireless hardware manufacturer
Ubiquiti networks, Pera is elusive about his personal life, but
he's not known to be dating anyone currently. As well as
having a net worth of $7.8 billion (£6bn), he's got a seriously
impressive résumé: he holds degrees in electrical
engineering and Japanese, and worked at Apple for two
years before braving it on his own.
Mikhail Prokhorov, 54, net worth: $9.8 billion (£7.5bn)
A jack of all trades, Russian oligarch Prokhorov has run
numerous companies, served in the Soviet army, purchased
a majority stake in Russian basketball team the New Jersey
Nets, and even ran for president against Vladimir Putin back
in 2012. He might be a busy man but he's often expressed his
desire for a partner, reportedly pledging that he's get
married if the New Jersey Nets hadn't won the NBA
championship in five years – a pledge which he later
retracted.
Jan Koum, 43, net worth: $9.9 billion (£7.6bn)
