According to Lil Tay's Instagram page, the internet personality died at the age of 14.
Her older brother, who was behind many of her antics, is also said to be dead.
As a nine-year-old, Tay charmed and horrified social media by speaking and flexing like a rapper.
Her page then went dark amid a custody fight between her parents.
The last post on Tay's IG page was a 2018 conversation she had with XXTentacion before he died.
RIP, Lil Tay.
