Rihanna has overtaken Lady Gaga to become the most popular female artist on Facebook.

According to social media statistics site Famecount.com, Rihanna passed Gaga early Thursday morning (July 14), with the Barbados native currently sitting at 40,598,000 Facebook fans compared to Gaga's 40,565,000 fans. However, Lady Gaga's Twitter presence -- 11.6 million followers and counting -- dwarfs Rihanna's 6.1 million followers on the site.
