She still has quite a bit of catching up to do, I doubt it will happen. That doesn't even make sense.
you doubt she's going to catch up?
she's about to get her 7th number one single from her SECOND ALBUM.
Rihanna got her 11th number one on her SIXTH ALBUM.
AND she was featured TWICE.
Does Billboard count Katy Perry's first album Katy hudson, because if they don't and Katy has 10 #1's in 5,5 years and beats Rihanna's record...
Bitch better hide.
With POM, Katy will have 8 #1's. Rihanna has 11. Katy will need 3 more #'1 to tie Rihanna and one more to beat her. And that's given if Rihanna doesn't make it to the top spot on BB100 in the next 2-3 years.
