It seems that all the hard work is paying off for Rihanna.

As she continues her gruelling promotional tour for her new album Rated R, the songstress just achieved her eighth number one single on the U.S. Billboard Chart this week with What's My Name.

The 22-year-old Bajan beauty has been in the French capital, Paris for the past couple of days making public appearances including stopping by Skyrock Radio for an interview alongside her baseball playing boyfriend Matt Kemp.
