At the young age of 23, Rihanna became the youngest artist to have 10 #1 hits on the Billboard Hot 100, with her #1 hit S&M
At the same time, she ranked 3rd place for shortest amount of time to get her 10th #1 hit on the chart (only behind the Beatles and the Supremes)
Fastest solo artist to get 10 #1 hits (4 years, 11 months, 2 weeks, beating out the previous record-holder Mariah Carey by over 6 months)
Rihanna is the only female artist to have 3 or more #1 hits on the Billboard Hot 100 from 3 different albums.
The ultimate hit machine indeed
