Yes! It's a confirmed single in Netherlands so most likely for the rest of the world too.

1265. Katy Perry - Birthday

On its way to #1.

Dark ***** who?

I was secretly hoping she was fooling us, just to release Legendary Lovers out of the blue

I'm sorry but I hate hate this song I think is the worst on Prism

She should've released LL

I've had this stucvk in my head all day and been bopping - I don't even use Prism
THIS is a HIT right in time for summer
The "Last Friday Night" of Prism

Yes!
Birthday was an instant listen for me. The track that made me go back and hit repeat. I'm biased maybe because I love Mariah and this just feels like old school mariah.

So much better than LL, which is meh in my book. Hope I'm wrong cause it's a confirmed single.

This wouldn't suprise me tbh

Birthday going to number 1 is icing on the cake. We had two monster number 1's this era. I'm content.

I would love 3, 4, 5 or even 6. But I am also a realist and would prefer to be surprised when it happens.

this won't be 1 mark me

Omg I heard birthday a second time today! On radio

This is going to pick up steam very quickly. Friends are already asking me about 'her new song'.

edit: Now wait. I see my local CHR station has started playing it. In fact they played Birthday at 11:06 and Dark Horse at 11:15.

I hope you are right!

La La La is coming though

omg I forgot about ha I hope Birthday dosen't get blocked from #1 by La La La
