La-da-da-da,
da-da-da,
la-da-da-da-da
La-da-da-da,
da-da-da
If I told you how much
I think about her
You'd think I was in love
And if you knew how
much I looked at
her pictures
You would think
we're best friends
'Cause I know her
star sign, I know
her blood type
I've seen every movie
she's been in and,
oh god, she's beautiful
And I know you loved
her, and I know
I'm butthurt
But I can't help it,
no, I can't help it
I'm so obsessed
with your ex
I know she's been
asleep on my side
of your bed
And I can feel it
I'm starin' at her
like I wanna get hurt
And I remember every
detail you have ever
told me
So be careful, baby
I'm so obsessed
with your ex
Yeah, I'm so obsessed
with your ex
La-da-da-da,
da-da-da
She's got those lips,
she's got those hips
The life of every
f*ckin' party
She's talented,
she's good with kids
She even speaks kindly
about me, ha-huh
And I know you
love me, and I know
it's crazy
But every time
you call my name,
I think you mistake
me for her
You both have
moved on, you don't
even talk
But I can't help it,
I got issues, I can't
help it, baby
I'm so obsessed
with your ex
I know she's been
asleep on my side
in your bed
And I can feel it
I'm starin' at her
like I wanna get hurt
And I remember every
detail you have ever
told me
So be careful, baby
I'm so obsessed
with your ex
Yeah, I'm so obsessed
with your ex
Is she friends with
your friends? Is
she good in bed?
Do you think about
her? No, I'm fine, it
doesn't matter, tell me
Is she easy-going?
Never controlling?
Well-traveled?
Well-read?
Oh god, she makes
me so upset
I'm so obsessed
with your ex
She's been asleep on
my side in your bed
I'm so obsessed with
your ex
I'm so obsessed with
your, with your ex
