Rihanna's first single "Work" (featuring Drake) from her latest album called "Anti" (album released on January 28, 2016) has just topped the US Billboard charts making it her 14th #1 single, just enough to beat Michael Jackson's record of 13 #1s.
Rihanna still has two more musicians to beat as Mariah Carey has a total of 18 #1 singles and The Beatles with 20 #1 singles.
Considering Rihanna's age (Bdate: 02/20/1988) and popularity, it is very much possible that she can beat Mariah Carey and The Beatles with most #1s in the future. Who would have thought that a certain girl from Barbados would someday become one of the most popular musicians in the whole wide world.
Here's the top 10 musicians with the most #1 singles in the US Billboard charts.
The Beatles = 20
Mariah Carey = 18
Rihanna = 14
Michael Jackson = 13
Madonna = 12
The Supremes = 12
Whitney Houston = 11
Janet Jackson = 10
Stevie Wonder = 10
