Boyfriend Ashlee
What can been doing?
What can been doing?
Oh Oh
Haven t seen you round
How you been feeling?
How you been feeling?
Oh Oh
Dontcha bring me down
All that stuff
About me
Being with him
Can t believe
All the lies that you told
Just to ease your own soul
But I m bigger than that,
No you don t have my back
No No (Ha)
Hey how long till the music drowns you out
Don t put words up in my mouth
I didn t steal your boyfriend
Hey how long till you face what s going on
Cause you really got it wrong?
I didn t steal your boyfriend
Well I m sorry
That he called me
And that I answered the telephone
Don t be worried
I m not with him
And when I go out tonight
I m going home alone
Just got back
From my tour
I m a mess girl for sure
All I want is some fun,
Guess that I d better run
