Rihanna has surpassed Lady Gaga's massive Facebook following to become the new "queen" of the social networking site.

RiRi reigns supreme, having just passed Gaga in number of Facebook fans -- 40,523,918 to 40,514,982! The achievement earns Rihanna the honorary title of "Queen of Facebook" from social media statistical tracker FameCount.

Rihanna may be the most popular female on Faceboook, but as far as famous recording artists in general go, Rihanna still trails "King" Eminem, who rules with a whopping 43,232,641 Facebook fans.

And when it comes to the other social media monster, Twitter, Gaga wins with a record 11,632,837 to RiRi's meager 6,099,406 followers.
