And the beat goes on I'm a happy girl
It's my birthday song in my happy world
I know it's gonna be a good day
Oh yeah today is my birthday huh
And the beat goes on (and the beat goes on)
I'm a happy girl (I'm a happy girl)
It's my birthday song (oh yeah it's my birthday)
In my happy world (in my happy world)
Light my candles gotta make a wish
Wrap up the present and seal it with a kiss
Gimme a spanking start the day off right (woo-wee)
'Cause it's my day you gonna sing my song tonight
And the beat goes on (and the beat goes on)
I'm a happy girl (I'm a happy girl)
It's my birthday song (oh yeah it's my birthday)
In my happy world (in my happy world)
I know it's gonna be a good day
Oh yeah today it's my birthday
I'm a happy girl (I'm a happy girl)
My type of party there's no hangover
So grab your things you better come over
We get high and we still stay sober
We throw it down and then we gonna start over
My type of party there's no hangover
And the beat goes on (and the beat goes on)
I'm a happy girl (I'm a happy girl)
It's my birthday song (oh yeah it's my birthday)
In my happy world (in my happy world)
I want a diamond don't give me a fake
I'll let you lick the frosting off my cake
Gimme a spanking start the day off right (woo-wee)
'Cause it's my birthday you'll be singing my song tonight
And the beat goes on (na na na na na na na na na)
I'm a happy girl (na na na na na na na na na)
It's my birthday song ((na na na na na na na na na)
In my happy world (na na na na na na na na na)
I know it's gonna be a good day oh yeah today is my birthday
