According to Famecount, the social media tracking service, the visually arresting pop diva Rihanna has now joined an elite social media club; she is the fourth artist in history to amass one billion views on YouTube.

Lady Gaga, Justin Bieber and Eminem have all topped one billion views on YouTube, so the 'Umbrella' singer is in good company with this accomplishment. In the social media/networking sphere, all eyeballs are on Gaga, Biebs, Em and RiRi!

It is worth nothing that Rihanna's duet with Eminem, the smash hit single 'Love the Way You Lie,' was critical in helping to push the singer over the billion views total mark -- the video received more than 300 million views on YouTube. Clearly, partnering up with Eminem helps your social media stock skyrocket.

Could Rihanna be the next in line for attaining the most Facebook 'likes?' Eminem recently surpassed Michael Jackson for the most Facebook 'likes' out of any fan page.
