One of Prince’s girlfriends during his wild days also died at 57 – after surviving being told she would die in 1992 due to crippling health problems.
Vanity, who had an intense, drug-fueled relationship with Prince in the 1980s, died in February due to kidney failure following years of crack cocaine abuse.
In her memoir she admitted that her lifestyle had left her needing 23 surgeries and dialysis three times a week.
At one point she was given just three days to live.
When she died Vanity had raised $6,709 towards her goal of $50,000 to cover her medical bills.
Prince’s body was found in the elevator of his estate in Paisley Park in Minnesota on Thursday.
