Bernard Ecclestone, #418 on the Forbes list, is worth $2.8 billion
Petra, 23, is the daughter of Bernard Ecclestone, CEO of Formula One and perhaps the most glamorous heiress on our list.
As we've reported before, Petra lives quite the luxurious lifestyle with multiple million-dollar estates across the world, including the former Spelling estate, once the most expensive home in America, for which she paid $85 million.
It is no surprise that Petra is a former model, but this heiress is a working girl as well. As an ambassador for the Meningitis Trust and an aspiring fashion designer with multiple lines, Petra proudly boasts about working 8 hour days.
Nevertheless, Petra's recent wedding cost £12 million with performances by Eric Clapton, The Black Eyed Peas and David Guetta; nothing big compared to Bernie's $2.8 billion net worth.
Sir David Barclay, #358 on the Forbes list, is worth $3.2 billion
Sofia Barclay, 23, is the granddaughter of David Barclay, media and real estate tycoon, estimated to be worth a combined $3.2 billion with her twin brother Frederick.
This beautiful heiress splits her time between London and New York City and attended Westminster School in London.
Sofia has said that she has always wanted to be an actress and has attempted to pursue her career in New York City. Considering her beauty and familial wealth, she should not have much of a problem.

Richard Branson, #255 on the Forbes list, is worth $4.2 billion
The son of Virgin mogul Richard Branson could very well pose as a double for his father, but he does far more than hide in Sir Richard's shadow.
Sam, 26, who graduated from St. Edwards in Oxford, has expressed an interest in becoming a documentary filmmaker and has mostly shied away from the public. However, the young heir is a known friend of Prince Harry.
A few years ago, Sam spent three months trekking across the Arctic and recently set up his own production company.
It is no surprise that the Virgin heir is frequently listed as one of Britain's most eligible bachelors.
Mukesh Ambani, #19 on the Forbes list, is worth $22.3 billion
The 20-year-old is currently a Sophomore at Yale and the only daughter of Mukesh Ambani, an oil tycoon and India's richest man.

Rumors have it that Marta, 28, is being groomed by her father to one day take over the international fashion company that owns the Zara retail chain.
However, Marta has been given no easy path and started at the bottom where she stocked shelves and dealt with customers. This may be hard work, but considering her father is worth $37.5 billion, it's probably worth it.
Marta is also an avid equestrian and recently married Spanish equestrian star Sergio Alvarez Moya.
Michael Bloomberg, #20 on the Forbes list, is worth $22 billion
Georgina is the daughter of Michael Bloomberg, who is not only New York City's mayor but the 20th richest person in the world. Georgina, the "rebellious" Bloomberg, has shunned the political and business world of her family to become a professional equestrian.

Vasily Anisimov, #330 on the Forbes list, is worth $3.4 billion

As Head of Communications for Louis Vuitton, Antoine Arnault is seemingly being groomed to follow in the steps of his father Bernard, CEO of the massive luxury company LVMH.
At 34, the Frenchman is on the older side of our list, but age does not seem to be an issue for Natalia Vodianova, Antoine's Russian model girlfriend.
Beyond frequently being known as a "boss" of the fashion world, Antoine enjoys a life of luxury on yacht rides along the coast of Corsica and is ranked as a professional poker player. With the net worth of his father at an estimated $41 billion, he can probably afford the vacation time.
Five of her relatives are worth $1.9 billion or more and are ranked by Forbes
The 28-year old is the heiress to the multi-billion dollar Hearst Corporation and graduated from Boston College with a major in art history. Although her parents may not be on the billionaire list, Amanda has five different Hearst family relatives ranked amongst the world's richest.
Amanda's great-grandfather is frequently cited as the creator of modern tabloid journalism, but Amanda tends to stay out of the spotlight herself. However, about a decade ago Harper's Bazaar published an article claiming the heiress spends $136,000 on herself annually, a figure she vehemently denies.
Beyond the wealth, Amanda has modeled for Tommy Hilfiger and is the founder of Friends of Finn, an organization dedicated to the closing of puppy mills.
Currently, Amanda is an associate market editor at Marie Claire.
This stunning Duke graduate is the only daughter of legendary fashion icon Ralph Lauren.

After breaking her leg, Anastasia has quit aquabiking to pursue a career in sports management.
Marc Lasry, #960 on the Forbes list, is worth $1.3 billion
Emma Lasry, 19, is the daughter of Marc Lasry, manager of hedge fund Avenue Capital Group.
As we reported back in 2010, Emma is an aspiring singer and made headlines when she released her first music video, "Closet Bitch" on YouTube. The video became an internet sensation, but not for the best reasons; online commenters took it as a prime example of another spoiled Wall Street heiress taking advantage of her father's deep pockets (it didn't help that Khloe Kardashian was paid to be in the video).
Now the video is down, but Emma seems to have continued working towards her dream of becoming a star by occasionally posting videos of her singing online. Watch her sing Adele's Set Fire To The Rain here.

Paul Tudor Jones II, #330 on the Forbes list, is worth $3.4 billion
As we've reported before, Caroline Jones, daughter of BVI Global Fund manager Paul Tudor Jones II is not only beautiful, she is a surprisingly talented singer/songwriter as well.
Caroline, 21, is not yet a household name but the folk artist has been working quite hard to change that as of late, performing at numerous high schools and universities as part of her "All Aboard" tour.
Coming from such a luxurious background seems to have its perks as Caroline has recorded with former Sony Music Entertainment head Tommy Mottola and played alongside Paul Simon and Dave Matthews last month in her hometown of Greenwich, Connecticut.
Beyond all the touring and recording, the starlet hopeful is currently studying creative writing at New York University.
