ROFLMAO. This song is WITHOUT FLAWS. Christina fans are surely jealous because it's everything that Keeps Failing Better wanted to be. In terms of ENERGY, CATCHINESS and overall QUALITY. 
LYRICS:
Superstar
Where you from, how's it going?
I know you
Gotta clue, what you’re doing?
You can play brand new to all the other chicks out here
But I know what you are, what you are, baby
Look at you
Gettin' more than just re-up
Baby, you
Got all the puppets with their strings up
Fakin' like a good one, but I call 'em like I see 'em
I know what you are, what you are, baby
Chorus:
Womanizer Woman-woman-izer you're a womanizer oh
Womanizer oh you're a womanizer baby
you-you you-you
Womanizer Womanizer Womanizer
Boy, don't try to front
I know just what you are
Boy, don't try to front
I know just what you are
You got me going
You open for me
So I can do it
Womanizer
Boy, don't try to front
I know just what you are
Boy, don't try to front
I know just what you are
You say I'm crazy
I got you crazy
You're nothing but a..
Womanizer
Verse:
Daddy-O
You got the swagger of champions
Too bad for you
Just can't find the right companion
I guess when you have one too many, makes it hard
It could be easy, but that's who you are, baby
Lollipop
Must mistake me as a sucker
To think that I
Would be a victim not another
Say it, play it how you wanna
But no way I'm ever gonna fall for you, never you, baby
Chorus:
Womanizer Woman-woman-izer you're a womanizer oh
Womanizer oh you're a womanizer baby
you-you you-you
Womanizer Womanizer Womanizer
Boy, don't try to front
I know just what you are
Boy, don't try to front
I know just what you are
You got me going
You open for me
So I can do it
Womanizer
Boy, don't try to front
I know just what you are
Boy, don't try to front
I know just what you are
You say I'm crazy
I got you crazy
You're nothing but a..
Womanizer
Bridge:
Maybe if we both lived in a different world
It would be all good, and maybe I could be ya girl
But I can't 'cause we don't
Womanizer Woman-woman-izer you're a womanizer oh
Womanizer oh you're a womanizer baby
you-you you-you
Womanizer Womanizer Womanizer
Boy, don't try to front
I know just what you are
Boy, don't try to front
I know just what you are
You got me going
You open for me
So I can do it
Womanizer
Boy, don't try to front
I know just what you are
Boy, don't try to front
I know just what you are
You say I'm crazy
I got you crazy
You're nothing but a..
Womanizer
Boy, don't try to front
I know just what you are
Boy, don't try to front
I know just what you are
Womanizer Woman-woman-izer you're a womanizer oh
Womanizer oh you're a womanizer baby
THIS IS A DRUG!
