Still, there are far richer celebs than 21-year-old Jenner and 49-year-old JAY-Z. The number one spot on the list goes to George Lucas ($5.4 billion) followed by Steven Spielberg ($3.7 billion), Oprah Winfrey ($2.8 billion) and Michael Jordan ($1.7 billion).
Jenner caused controversy in July when she appeared on the cover of Forbes' "America's Women Billionaires" issue and the magazine noted that she was on track to become the youngest self-made billionaire ever. Some took issue with the "self-made" description, given her famous family.
"You know, everyone has a team, I don’t care who you are," Kardashian West noted. "But when you don’t get it from someone else, that's 'self-made.' It’s not like that was handed to her. She figured that all out. I mean, we all have."
Jenner's mother, Kris Jenner, also praised her youngest child to ET.
"She made her own money for over a decade, she put it in the bank, she saved every nickel," Kris recalled of the days before Kylie Cosmetics started. "And then, when she decided on what she wanted to do, she spent her money on a venture that could have gone south or north, and it did really well."
