As of this writing, Dixie D'Amelio is worth $3 million, per Celebrity Net Worth. Her high profile means that she has had all sorts of sponsorships and brand deals, and she's the third highest-earning TikTok celebrity of 2020, behind only her sister and Addison Rae.
Both of the D'Amelio sisters have earned their money — they weren't born into wealth. Their father, Mark D'Amelio, was a Republican candidate for the Connecticut State Senate in 2018, per Insider, while Heidi D'Amelio, their mother, worked as a model and a personal trainer. The family moved to Los Angeles from Connecticut in light of the sisters' popularity. After making the move, for a time, Dixie and Chali were members of the TikTok collective Hype House.
Additionally, there's an eight-part documentary series on Hulu to come from the family and with Dixie still yet to enter her twenties, she's got plenty of time to add to her $3 million fortune. Her music career is still moving along steadily, and it seems like she's set to become an even bigger star in the coming years.
