Well, if it follows the patterns of her recent albums, that only means one more #1 coming, so it's nothing to get too shaken over. Katy will get that this year, too. So they can remain at the top together.
Mess, let the #Katyanna in, cats, navy, let the haters out please enjoy our faves success they can rule the music industry together as they have been doing since 2010
Katycats and Navy should just be happy for Katy and Rihanna's success. Katy is getting all these success because she puts alot of effort on her records and works hard, Rihanna has THE VOICE that people writes songs for her to turn into hits and she's likely to collect many number 1s in the future since she's VERY Young so there's no need for fighting they're both amazing
Katy slaying. and not some people trying with Katy is only for children when "Roar" has spend 10 weeks at #1 on AC and she has 8 #1s on HAC, basically she's the queen of 24-49 demo on the radio
Um...Rih has had a #1 every year since 2010.
2010: Only Girl, What's My Name, S&M, Love The Way You Lie
2011: We Found Love
2012: Diamonds
2013: The Monster
Technically, The Monster was the first #1 single of 2014 and that means Rihanna had the rihcord first.
you've missed Rude Boy
and S&M got to #1 in 2011
but I think you know it
and, yes, of course she'll get #1 this year, so that's not a problem
Except billboard already give biggest artist of the 2010s to Rihanna
Nope, they said that Rihanna was the biggest artist of the 2010s on the Hot 100 so far, not that she is the artist of the decade. Get your facts straight.
I must have missed that, too 
they're both amazing
