Rihanna Ties For Highest Pop #1s

Rihanna reaches a milestone in music met only by three other artists in history.

With Emimem's "Love The Way You Lie" reaching the Pop Songs No. 1, Rihanna - who is featured on the single - ties the mark for most No. 1s in the Nielsen survey's 18-year history.

According to Billboard, Rihanna's six Pop Songs No. 1s are equaled only by Mariah Carey - who topped the chart between 1993 and 2005, Beyonce (2003-10), and Lady Gaga (2009-10).

The achievement puts Rihanna over Avril Lavigne, Pink, Britney Spears and Justin Timberlake, who each have five Pop Songs No. 1s.

Rihanna's other Pop Songs No. 1s include "SOS," "Take a Bow," "Disturbia," "Live Your Life" (T.I. featuring Rihanna) and "Rude Boy."

"Love the Way You Lie" is Eminem's third Pop Songs No. 1, a mark he reached twice with "Without Me" and "Lose Yourself."
