Kylie Jenner About To Become Youngest Billionaire Kylie Jenner is on her way to becoming the youngest “self-made” (as per Forbes) billionaire in history. The reality star amassed $630 million in sales within three years through her cosmetic line which she completely owns.

The magazine predicts that Kylie’s net worth will most likely reach $1 billion by next year, making her the youngest billionaire ever.

The beauty mogul is turning legal next month, which is certainly a milestone aside from her hefty bank account.
