I can hear
A little voice inside my head
Telling me
That I should do what she says
Looking over my shoulder 
She trying to tell me things 
Always misleading me
Nobody can see
I can be good, she can be bad
We can be this and that
She's my alter ego
When I want to be weak 
She can be strong 
All rolled into one
She's my alter ego
I can tell
When she's about to pull me in
She has no fear 
But then she doesn't always win
Looking into the mirror
She trying to have fun with me 
Sometimes I take myself way to seriously
I can be good, she can be bad
We can be this and that
She's my alter ego
When I want to be weak 
She can be strong 
All rolled into one
She's my alter ego
It's like she sometimes my best friend 
Then my enemy again
She is no where
But she's always there
Yeah 
Oh yeah
I can hear a little voice inside my head 
Telling me I should have done what she said, yeah
I can be good, she can bad
We can be this and that
She's my alter ego
When I'm little miss perfect
She misbehaving 
I take the blame
She's my alter ego
I can be good, she can be bad
We can be this and that
She's my alter ego
When I want to be weak 
She can be strong 
All rolled into one
She's my alter ego
I can be good
She can be bad
We can be this and that
Oh, oh yeah
She's my alter ego
