"Father-daughter bubble tea time," read a caption under a TikTok post from 21-year-old Phoebe Gates, posted on October 5.
In the clip, which has received 11.7 million views and uses "As It Was" by Harry Styles as a backing track, Phoebe sits opposite her billionaire father, Microsoft co-founder Bill Gates, as they both poke straws into cups of bubble tea and smile at one another overlooking a Manhattan skyline.
Bill Gates has made appearances on other creators' TikTok accounts in the past, often participating in math or art challenges, although he does not have an account himself.
Phoebe, however, has been posting on TikTok since at least last year and has now accumulated over 157,000 followers on the app. She gained over 59,000 of these followers the day after she posted the bubble tea video with her father, according to analytics website Social Blade.
Though her father, one of the richest people in the world, is a household name, little is known about 21-year-old Phoebe, the youngest of the billionaire's three children, outside of what she posts on social media.
Here's what we can learn about her life and interests based on what she has shared on TikTok.
