You moved like magic
You moved like time
You had your heart disguised
When you cry diamonds
Yeah, they shine
But they blind my eyes
And now

I hear the whispers every night
Even when I'm dreaming
Now tell me, baby, were you ever mine?

I wanna know who's in your head
Stealing your heart while I'm still bleeding
Who's in your bed?
Wrapped in your arms, while I ain't sleeping
Got lost in your halo, halo
I just wanna know
Now, who's in your head, in your head?
I wanna know who's in your head, in your head

You move like danger (huh)
But I don't mind (yeah, yeah)
The way you talking with your eyes, yeah (your eyes)
You leave me broken
And I can't lie (I can't lie)
It gets me every time
And now

I hear the whispers every night
Even when I'm dreaming
Now tell me, baby, were you ever mine?

I wanna know who's in your head
Stealing your heart while I'm still bleeding
Who's in your bed?
Wrapped in your arms, while I ain't sleeping
Got lost in your halo, halo
I just wanna know
Now who's in your head, in your head?
I wanna know who's in your head, in your head

You get me down
On my knees, on my knees, yeah
You drive me wild
When you want, when you want it
Oh, you get me down
On my knees, on my knees, yeah
'Cause every time I look into your eyes (look into your eyes)

I wanna know who's in your head
Stealing your heart while I'm still bleeding
Who's in your bed?
Wrapped in your arms, while I ain't sleeping
Got lost in your halo, halo
I just wanna know
Now who's in your head, in your head?
I wanna know who's in your head, in your head

(In your head still, baby)
(In your head, when you're sleeping)
(In your head still, baby)
(In your head, when you're sleeping)
