Hey you, I saw you cross the room
I couldn't get you off my mind
I know I might not have a chance
But baby I got all night

Just like a fantasy
Something be moving me
it's like you're meant to be mine
You never know so fast
I knew it wouldn't last
it's like a perfect crime
You told me nothing lasts forever

I want you, I need you
Do you wanna be my ex-girlfriend?
it's so true, I can't keep you
Do you wanna be my ex-girlfriend?
Why I'm not surprised when you're breaking my heart?
So tell me
Do you wanna be my ex-girlfriend?

Do you wanna be my? do you wanna be my?
Oh oh (ex-girlfriend!)
Do you wanna be my? do you wanna be my?
Oh oh (ex-girlfriend!)

You tell all your little friends
That I'm just another guy
I'll say you could be the one
But I decide to say goodbye

You tell me you always knew
Love don't always come true
I guess it wasn't our time
But baby I can see
That you're still into me
let's give it one more try
I know that nothing lasts forever

I want you, I need you
Do you wanna be my ex-girlfriend?
it's so true, I can't keep you
Do you wanna be my ex-girlfriend?
Why I'm not surprised when you're breaking my heart?
So tell me
Do you wanna be my ex-girlfriend?

Hey you, I saw you cross the room
I couldn't get you off my mind
You said this will never work
But I don't care if it don't last forever

I want you, I need you
Do you wanna be my ex-girlfriend?
it's so true, I can't keep you
Do you wanna be my ex-girlfriend?
Why I'm not surprised when you're breaking my heart?
So tell me
Do you wanna be my ex-girlfriend?

Do you wanna be my? do you wanna be my?
do you wanna be my? (ex-girlfriend!)
Do you wanna be my? do you wanna be my?
Do you wanna be my? (ex-girlfriend!)
