I think so. Mariah has only 1 #1 in UK and 0 #1 in France
While Rihanna has 3 #1's in France and 5 #1's (6 with RTT)
Mariah has 3. Rihanna's only had 2 more in the UK. 18 - 11 = 7. That 7 left over covers Rih's #1's in the UK, with 2 left, that 2 covers most of France with Rihanna having 1 left for France. IF Rih beats Mariah it will be by very little because Mariah's 18 in the US is bigger than most totals
