Lyrics for Katy Perry – Birthday

[Verse 1:]
I hurt your feeling, nothing’s going bright
Why don’t you let me stop the vibe
The clock is ticking, running out of time
So we should party, all night
So cover your eyes, I have a surprise
I hope you got a healthy appetite

If you wanna dance, if you want it all
You know that I’m the girl that you should call

[Hook:]
But when you’re with me
I’ll give you a taste
Make it like your birthday everyday
I know you like it sweet
So you can have your cake
Give you something good to celebrate

So make a wish
I’ll make it like your birthday everyday
I’ll be your gift
Give you something good to celebrate

[Verse 2:]
Pop your confetti
We can get it on
So hot and heavy
Till dawn
I got you spinning
Like a disco ball
I’ll have them playing
Your song

We’re living the life
We’re doing it right
You’re never gonna be unsatisfied
If you wanna dance
If you want it all
You know I’m the girl that you should call

[Hook:]
But when you’re with me
I’ll give you a taste
Make it like your birthday everyday
I know you like it sweet
So you can have your cake
Give you something good to celebrate

So make a wish
I’ll make it like your birthday everyday
I’ll be your gift
Give you something good to celebrate

Happy birthday

So let me get you in your birthday suit
It’s time to bring out the big balloons
So let me get you in your birthday suit
It’s time to bring out the big, big, big, big, big, big balloons

[Hook:]
But when you’re with me
I’ll give you a taste
Make it like your birthday everyday
I know you like it sweet
So you can have your cake
Give you something good to celebrate

But when you’re with me
I’ll give you a taste
Make it like your birthday everyday
I know you like it sweet
So you can have your cake
Give you something good to celebrate

So make a wish
I’ll make it like your birthday everyday
I’ll be your gift
Give you something good to celebrate

Happy birthday
