The youngest person to ever make an appearance on the Forbes list, Kylie Jenner's fortune is more than twice as large as her second-eldest sister, Kardashian West, who Forbes listed as worth $350 million.
Either way, this Jenner seems to be proud of how far she's come!

Forbes' Natalie Robehmed detailed how Kylie Cosmetics has found success by harnessing Jenner's huge social-media following and slashing costs by outsourcing labor.
The 20-year-old with her seemingly unstoppable makeup empire, Kylie Cosmetics, is one of seven newcomers on the list, which includes the likes of her sister Kim Kardashian.
When adding into account her product endorsements with brands including Puma shoes and PacSun clothing, the reality TV star's net worth is estimated to around $900 million.
Kylie Cosmetics is dealing with slowing growth - Forbes reports that revenue grew just 7% past year, with lip-kit revenue dropping an estimated 35%.
"Social media is an wonderful platform; I have such easy access to my fans and my customers".
The 20-year-old, who launched her own cosmetic line, Kylie Cosmetics, less than three years ago, has already accumulated more than $900 million. At the time, Kris Jenner, Kylie's mother, who rakes in 10 percent of all her children's earnings, said the company had collected $420 million in retail sales over 19 months.
Speaking on Kylie's rise, Forbes wrote, "Another year of growth will make her the youngest self-made billionaire ever, male or female, trumping Mark Zuckerberg, who became a billionaire at age 23".
"Ever since I was in sixth grade, I would wear purple eye shadow", she remembers.
"I said, 'I'm ready to put up my own money. I turned to makeup to help me feel more confident".
Jenner told Forbes that she invested $250,000 of her own money from modeling gigs in 2015 to pay an outside company to produce the first 15,000 lip kits that eventually launched into a full-fledged cosmetic line. She has become so dominant on social media that when she tweeted that she had become bored with Snapchat, its parent company's stock lost 6% of its value within a day, around $1.3bn.
