LYRICS:

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 (uh-huh)

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 (ah)

Yeah, I'm so obsessed with your ex (ah)

La, da-da-da, da-da-da

She's got those lips, she's got those hips

The life of every fuckin' party

She's talented, she's good with kids

She even speaks kindly about me, ah-ah

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 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 (ah)

Yeah, I'm so obsessed with your ex (ah)

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? Ever controlling?

Well-traveled? Well-read? Oh God, she makes me so upset

I'm so obsessed with your ex (ah)

She's been asleep on my side of your bed (ah), whoa

I'm so obsessed with your ex (God, she makes me so upset)

I'm so obsessed with your, with your ex
