Ally Hilfiger, $400 million
Ally is a socialite and heir to the Tommy Hilfiger fortune. The brand is an American classic when it comes to fashion. Her childhood was "ravaged" by her struggle with Lyme disease, and today she is an author and activist who spreads awareness about the disease.
North West, $130 million
It's no surprise that the oldest daughter of Kim and Kanye is worth this much. Believe it or not, she's actually earned quite a bit of that money all on her own. She's appeared in commercials, TV, and some music videos thanks to her dad.
