Lyrics:

So there's ..
There's a reason that you're in my head
And there's a good reason why you're in my bed
'Cause there's a reason now that you're my girl
There's a reason that ... you ... rock .. my ... world
You rock my world
You rock my world

'cause you're dirty
But you got a good heart
D-D-D-Dirty
But you're not a cheap tart
Yeah, you're dirty
But you got a good heart
D-D-D-Dirty
But you're not a cheap tart

There's a reason why you're in my head
There's a very good reason why you're in my bed
Oh, there's a reason now that you're my girl
There's a reason why you rock my world

'cause you're dirty
But you got a good heart
D-D-D-Dirty
But you're not a cheap tart

There's a reason why you're in my head
There's a good reason why you're in my bed
There's a reason now that you're my girl
There's a reason why ... you ... rock .. my ... world
You rock my world
You rock my world

'cause you're dirty
But you got a good heart
D-D-D-Dirty
But you're not a cheap tart
Yeah
