Charli and Dixie D'Amelio Charli and Dixie D'Amelio have become household names all thanks to TikTok. Charli, at just 16 years old, is the most-followed person on the app with her 82.4 million fan base, and older sister Dixie's follower count at 18 years old is nothing to scoff at: 35.8 million. While the pair make content ranging from dance to funny sibling videos, they've each had their fair share of beauty partnerships with different brands. Dixie scored her first beauty campaign with the brand Clear Start before the duo went on to partner with Morphe Cosmetics for the Morphe 2 collection and create their own summer nail polish collection with Orosa Beauty.
