Rihanna Edges Her Idol Mariah as Youngest Artist with 10 #1s

Rihanna's latest single, "S&M," hit #1 on the Billboard Hot 100 chart, giving the Pop star her tenth #1 hit single. This means that Rihanna also makes history as the youngest artist ever to rack up ten #1 hits at just over 23-years-old. Mariah Carey held the previous record when she was 25. Furthermore, Rihanna is also the ninth artist in history to have ten #1 hits, and she is the fifth solo female artist to do so, following Carey (18), Madonna (12), Whitney Houston (11) and Janet Jackson (10).
