[Chorus]
Some days I'm a super bitch
A super...
But it won't last forever
Some days I'm a super bitch
Super girl
It keeps gettin' better
It keeps gettin' better
It keeps gettin' better
It keeps gettin' better
It keeps gettin' better
(Super...)
But it won't last forever, no
It keeps gettin' better
It keeps gettin' better
Super girl
Keeps gettin' better
It keeps gettin' better
It keeps gettin' better
Some days I'm a super bitch
Some days I'm a super bitch
It keeps gettin' better
It keeps gettin' better
It keeps gettin' better
Super girl
It keeps gettin' better
It keeps gettin' better
A super...
But it won't last forever, no
Super girl
It keeps gettin' better
Super girl
It keeps gettin' better
Super girl
It keeps gettin' better
It keeps gettin' better
