Controversy is never far from the Kardashian family.

But its not babies or boyfriends grabbing the headlines this time, but Kylie Jenners new status as the worlds youngest self-made billionaire.

Jenner, who hasearned a 10-figure fortune aged 21, gained global recognition in her familys reality TV show Keeping Up with the Kardashians.

Though Jenner has made her fortune with her best-selling beauty business, Kylie Cosmetics, some have questioned whether her money can really be self-made, since she comes from such a privileged background.

Jenner welcomed her billionaire status with a post on Instagram thanking Forbes for the recognition.

Shes also defended the notion that shes self-made,telling Paper Magazine last month that none of her money is inherited.

In that interview, Jenner said the self-made thing is true.

She claims her parents, Kris and Caitlyn Jenner, cut her off at the age of 15 and told her to start making her own fortune.

Jenner, who stars in the reality show Keeping Up with the Kardashians, continued: What Im trying to say is I did have a platform, but none of my money is inherited.

Forbes has also weighed in on the issue, saying: To be clear, Forbes defines self-made as someone who built a company or established a fortune on her own, rather than inheriting some or all of it.

The magazine has devised a scale ranking how truly self-made a business person is.

On Forbes scale, media mogul Oprah Winfrey, who was born poor, scored a 10. Jenner, who has benefitted from being born into a famous, wealthy family, scored seven.

Bybreen Samuels, author of the business book Non-Profit Booster – 10 Steps to Building a Successful Organisation, believes describing Kylie Jenner as a self-made billionaire is a misnomer because at no time has she faced true entrepreneurial challenges.

Samuels adds Jenners journey to becoming a billionaire is in stark contrast with that of Sara Blakely, who used all her $5,000 (3800) savings to launch the slimming knickers Spanx.

Forbes named Blakelythe youngest self-made female billionaire in 2012, at the age of 41.

Samuels tells BBC News of Jenner: She gained leverage by using her family name, fame and wealth. Consequently, she had direct access to the whole range of privileges, connections and resources that flow from these factors.

Her ascendancy into global wealth and brand recognition was already guaranteed before she even started.

Predictably, given Jenners background, opinions on social media about her self-made status are split.

Jenner was 10 years old when she made her debut on her familys reality TV series.

A decade on, shes the famous familys highest earner.

Freelance beauty journalist Jessica Morgan says Jenners achievement shouldnt be underestimated.

If Jenner hadnt come from a famous family, perhaps she wouldnt have been named the worlds youngest billionaire so quickly, she tells BBC News.

But thats not to say she wouldnt have achieved such an accolade in her lifetime.

Her empire consists of seven full-time and five part-time employees.

Jenner trademarked the phrase Kylie Lip Kits … for the perfect pout two years before setting up her company.

She founded the brand with $250,000 (190,200) she made through modelling and TV work.

Her mother, Kris, looks after finance and PR in exchange for a 10% management fee.

Morgan continues: On average, it takes a millionaire 14 years to reach billionaire status while the average age to hit this status is 37.

It took Microsofts Bill Gates five years to reach billionaire status, while Amazons Jeff Bezos was crowned a billionaire after two years.

Im really happy for Kylie and Im excited to see what else she has in store for us.

With more than 175 million followers across Facebook, Instagram, Snapchat and Twitter, social media has been the key to Jenners success.

So influential is she, thatshe wiped $1.3bn (1bn) off Snaps stock market valueafter tweeting that she no longer used its Snapchat messaging app.

In May 2018,People reported that Jenner is the most valuable celebrity on Instagram, with each of her sponsored posts valued at around $1m (750,000) in traditional advertising spending.

Morgan says beauty brands that use social media effectively can achieve huge success: Emily Weiss built her beauty empire off the back of her blog, Into The Gloss, which garnered a huge following and subsequently led to Weiss launching Glossier.

Jenner and Weiss both have one thing in common: they built their businesses using social media as a free marketing tool and it has worked. We cant argue with that.
