It has been a steady climb for Rihanna as she has finally settled into the upper echelon of elite pop stars. Billboard reports that that she further cemented this status on Tuesday (June 18) by becoming the most viewed artist on YouTube. This is based on the cumulative views on her official VEVO channel on YouTube. Her 77 videos on this channel have a combined 3.784 billion views, which is a little over a million more views than Justin Bieber's 3.783 on his official VEVO channel. Justin has 79 videos altogether.
