Thanks to the recent mega-success of her collaboration with Eminem, for "Love the Way You Lie," Rihanna has earned a spot among only four females with six no. 1 Pop singles.

It was Mariah Carey who scored the accomplishment first, with singles between 1993 and 2005, but Beyonce and Lady Gaga caught up with her in March, when their single "Telephone" pushed them both to six no. 1 singles each.

Now, RiRi becomes the four female to earn six, with the help of Eminem.

Here's a recap of Rihanna's chart-topping singles: "S.O.S." in May 2006, "Take a Bow" in July 2008, "Disturbia" in October 2008, "Live Your Life" ith T.I. in December 2008, "Rude Boy" in May 2010," and her feature on Em's "Love The Way You Lie."

Avril Lavigne, Pink, Britney Spears and Justin Timberlake share the second-highest Pop Songs No. 1 total, each having five, reports Billboard.

Although tied in the Pop Songs category, Billboard says Rihanna has logged seven no. 1s on the Hot 100 singles chart, the most among any artist ... with Timberlake second with just four.
