According to Billboard, Rihanna now trails only the Beatles (20 #1s), Mariah Carey (18) and Michael Jackson (13 solo #1s) for the most Hot 100 chart toppers of all time, and, given that she's just 24 — and seemingly releases a new album every year — well, we think she's got a pretty realistic shot at overtaking all of them.
Rihanna also became the fastest female solo artist to accumulate 12 #1 singles, reaching the mark in six years and seven months ... that number trails only the Beatles (two years, four months) and the Supremes (five years, four months).
